Mai gasped, horrified. "Bakura! Hey, kiddo, are you alright?!" She knelt down next to the cavity worriedly, staring into the darkness. "Hey! Say something!"

A groan came from below.

"Oh no," Mai whispered and hurried to find something she could use to get into the basement. After a thorough search that turned up nothing, she finally found an old dumbwaiter. "Hmm . . . I wonder if this old trap still works," she mused. She climbed inside and operated the rope, causing the rickety, old-fashion elevator to descend to the floor below. Quickly she shoved the panel open and looked around. "Bakura? Are you down here?"

"He's here," Yami Bakura's familiar, gravelly voice spoke up from somewhere in the pitch black room. A bright light—which Mai realized was coming from the Millennium Ring—suddenly bathed the room in a soft glow, revealing that Yami Bakura was cradling the young boy on his lap. Bakura's eyes were closed, but Mai could see his chest was rising and falling and she breathed a sigh of relief. "He just had the wind knocked out of him," the tomb raider told her. "The fool was lucky he landed on that sack of grain instead of on the cement floor."

"Sack of grain?!" Mai repeated. "What's a sack of grain doing in an abandoned house?!"

Yami Bakura's eyes narrowed. His shoulder was bothering him again, but he wasn't about to admit it. "I intend to find out," he vowed.

"It must be after midnight!" Tea exclaimed as she, Yugi, and Seto climbed over the gate leading into the studio. "Why are there so many lights on in here?!"

"And what's that thing?!" Seto demanded, indicating a huge, saucer-shaped object just up ahead.

"A UFO!" Yugi gasped.

"Just don't tell me it's full of little green men from Mars," Seto muttered sarcastically.

"Alright then, I won't," Yugi replied with a vague smile.

As they got closer, an army of alien-like creatures sprang out at the teens, jabbering and glaring.

"More aliens!" Tea shrieked. "Are these robots too?!"

Seto batted at one that tried to shoot him down with its laser gun and the creature shattered into metal pieces. "It would appear that way," he remarked.

Using the Millennium Puzzle, Yugi raised his hand and threw the mechanical Martians against the nearest building, deactivating all of them at once. "We must enter the UFO," Yugi declared. "But we must tread cautiously."

As they slowly went up the open ramp, Tea turned to Yugi worriedly. "Yugi, you did tell your grampa where we were going, didn't you?"

Yugi nodded. "If he hasn't heard from us within three hours, he will notify the authorities."

The three teens stood in the doorway, surveying their new and unique surroundings. A control panel lined one wall of the room they had entered, and several doors leading to other rooms adorned the opposite one. It looked like the classic "alien movie" set.

"Is this for the movie?" Tea wondered aloud.

"It's possible," Yugi nodded. "Certainly more probable than the thought that it truly is from another planet."

There was silence as they glanced around at the control panel, and then suddenly a sharp, tinny voice yelled, "Intruders! Intruders!" and a strange barrel turned to face them.

"They're going to shoot us!" Tea screamed.

"Everyone scatter!" Yugi ordered. "Pick a door—now!"

Tea, Seto, and Yugi each ran through a different door as the automatic computer began to fire the gun. Laser fire exploded all around the doors they had passed through, very narrowly missing hitting any of them. But now they had a new problem—they were all separated from each other, and they didn't dare go back into the control room.

Yugi found himself standing in a strange corridor and decided to follow it along for a bit.

Tea was in an oddly-lighted room that looked a bit like an alien's living room, with strangely-shaped furniture and fruit in a basket on a table. She decided to make the best of things and try to look for any possible clues.

Seto wound up falling down a strange tunnel that was almost like a long playground slide. His hair flew wildly across his face and into his eyes and he let out an involuntary scream as his flight was suddenly speeded up. He had no idea where or when he would crash, but he had the feeling that he wasn't going to like it.

Oliver Brown climbed out of the window and grabbed Joey and Tristan before they could run away. "Punk brats," he muttered. "Your meddling days are over!"

"Man, Kaiba said he didn't trust you!" Joey burst out. "Was he right?"

Oliver sneered. "Well, you'll just have to decide that for yourself, Joseph." He pulled out a gun and pointed it at them. "Now . . . you're both coming with me, and if either of you tries anything stupid, someone will get hurt," he growled.

Joey and Tristan walked along obediently, conversing in undertones.

"Man, Joey, now you've really gotten us into a jam," Tristan remarked angrily.

"Hey, he probably would've found us soon enough anyway," Joey protested lamely. He glanced around. "And where in the world did Cindy go?!"

"I guess we can hope she went for help," Tristan muttered.

Oliver forced the two boys into his house and shoved them viciously to the floor. "Now," he snarled, towering over them with the gun, "I'm sure you've heard the idiom 'curiosity kills the cat.' You're about to find out that cats aren't the only creatures to die after meddling in things they shouldn't." He raised the gun high, placing his finger dangerously on the trigger.

"Hey, it's been great knowin' ya, pal," Joey said to Tristan.

"Same here," Tristan said with a nod.

Suddenly Joey gasped and pointed at something just behind Oliver. "Oh man!" he exclaimed. "It's the Abominable Snowman!"

Tristan, catching on, also gasped. "And E.T.!" he added.

"What? Where?" Oliver whirled around.

With a sneer, Joey lashed out and kicked at the man, knocking him down. The gun flew out of his hand, firing harmlessly into the floor.

"Man, I can't believe he fell for that old gag," Tristan grinned.

Joey grinned too, sitting on the man's back to restrain him from getting up. "Well, it looks like ol' Joey got us both out of a rushed trip to the afterlife!" he bragged. He looked down at Oliver, who was muttering something under his breath. "Now . . . wanna tell us exactly what's goin' on around here?" he asked.

"Ridiculous adolescents. . . . I don't have to tell you anything!" Oliver growled.

"Fine. Have it your way," Joey shrugged.

"I intend to," Oliver said with an evil sneer.

"Is it just me, or do you get the feeling that he has a backup plan?" Tristan remarked.

"Man, I get that feeling too," Joey groaned.

A panel in the wall opened and a vicious-looking army of aliens appeared, being led by a familiar human girl holding two laser guns. "Prepare to meet your doom, boys," she purred in a voice quite different from the cheerful, bubbly one the teens had known.

Joey and Tristan gasped. "Cindy!"

After Bakura recovered, Yami Bakura went back into the Millennium Ring and Bakura and Mai tried to figure out the mystery behind the baffling sack of grain.

"Why don't we go up into the attic?" Bakura suggested. "It's right under the roof where the aliens disappeared. Who knows? Maybe we'll find some good clues there."

"I'm game," Mai replied with a shrug.

It didn't take too long to find their way into the attic, and soon the two teens were poking around amongst the old junk and cobwebs.

"Hey, check this out!" Mai exclaimed suddenly, pointing to a perfect square cut in the attic's ceiling. "Is this what I think it is?"

Bakura came over to look. "Good show!" he said excitedly. "This is a trapdoor. Mai, I do believe you've solved the mystery of how the aliens vanished so abruptly. They must have re-entered the house through this door and then stayed hidden in a secret room somewhere in the house until the police concluded that no one was around!"

A nasty cackle echoed throughout the building.

"Oh dear!" Bakura gasped.

"Hey, kiddo . . . that wasn't your Yami by any chance, was it?" Mai asked.

"No, it wasn't," Bakura replied, shaking his head.

"I was afraid of that," Mai sighed.

The tunnel seemed to go on forever, twisting and turning and then spiraling downward. Seto found himself getting very dizzy. His wild ride stopped suddenly when the slide came to an end, sending him flying through the air and crashing to the hard floor below. The boy grunted in pain and slowly got to his feet, looking at his surroundings curiously. He recognized the room—its bright lights, the table with its odd instruments, the blood-splattered walls—the latter of which made him wince—and suddenly he remembered almost everything.

He had been suspicious of Carmichael ever since he had first rented the property and had started an investigation to find out what kind of person the guy was. What he had found out wasn't pretty.

Carmichael's real name was Alfred Hartman and he was a traitor, an enemy spy running from the government. He had set up the ruse of filming the alien movie, but in reality he was using the place to hide from the authorities. What's more, he and all of the movie's crew members were part of a secret organization bent on world domination. Seto had been going to call in the authorities and confront Carmichael with what he knew, but he had been ambushed by about a dozen members of the secret society before he could. Seto was a strong fighter who was perfectly capable of taking care of himself, but these men—all tough, Arnold Schwartzenegger types—had ganged up on him and then had shot him in the chest with one of the weapons they had created in one of their cryptic meetings, knocking him out. That was probably where the odd mark had come from, he decided now as he slowly walked around the room.

When Seto had woken up, he had been chained to the wall and those same men were beating him viciously, showing no mercy. Then Carmichael had come in with a deadly laser gun, prepared to end the boy's life for knowing too much. Seto, always clever, had kicked out and knocked one of the men backwards into Carmichael, sending them both to the floor and the laser gun across the room.

Things got a bit blurry after that. Seto still couldn't remember how he had gotten away and he glared at the room, the unpleasant memories angering him. "You won't be able to run forever, Carmichael," he muttered.

A panel in the wall opened and Tea fell in, looking shocked.

Seto was shocked as well. "What are you doing here?!" he demanded.

Tea stood up and looked around. "I . . . I fell down here," she said slowly. "I was up in some weird room and I opened a panel in the wall or something. . . ." She trailed off, staring at the room in horror. "What is this place?!"

"You don't want to know," Seto replied, steering her away from the blood-stained wall.

"It looks like a torture chamber!" Tea cried, her eyes wide.
Seto didn't answer.

"Cindy, what're you doing?!" Joey exclaimed, backing up.

The girl smirked. "It's been fun hanging out with you, Joey, but all good things must come to an end." She moved closer, stroking Joey's cheek with the barrel of one of her laser guns.

Joey pulled away in disgust. "Man, Cindy, I thought you were a sweet girl! How could you do this?!"

Cindy tossed her head. "Very easily. I've been infiltrating your little group all this time, finding out your suspicions, your suspects, and where you'd be investigating next."

"Whoa, so you've been working for the bad guys this whole time?" Tristan looked horrified.

"That's right," Cindy smirked. "And now you two will both die!"

"But I thought Oliver Brown was one of the good guys!" Tristan burst out in complete confusion.

"Nothin' makes sense!" Joey said in frustration.

"Well, he may be Carmichael's business partner, but he's secretly working as his rival," Cindy told them with a sneer. "It's him, not Carmichael, who's working with the mysterious 'aliens' to take over the world. Carmichael wants to rule the world too, but he doesn't have an alien army backing him up, only his pathetic followers in his secret society."

"When Carmichael came over today, he didn't say anything about you kids," Oliver said. "He was just angry about the uproar at his studio and wondered if I knew something about it."

"But Oliver knew that you guys had talked to Carmichael, thanks to me," Cindy put in, "so he pretended that that's what Carmichael had come to tell him."

Tristan looked nervously at Joey. "Why is it that the crooks always reveal their plots right before they kill the good guys?" he gulped.

"Don't worry!" Joey tried to sound confident as they were surrounded on all sides by Oliver, Cindy, and the alien-creatures. "I'll think of something."

"Yeah, but will it be too late?" Tristan shot back as their captors' guns all clicked, prepared to fire.

Bakura and Mai stood tensely in the shadows as mysterious footsteps grew closer, coming up the stairs and then stopping just outside the door. Yami Bakura came out of the Ring to join the nervous teens.

"Yami, you're too weak to fight!" Bakura gasped.

Yami Bakura growled in reply. "Who goes here?" he yelled.

There was a long silence, and then a familiar voice said slowly, "Yami Bakura?"

"Yugi?" Mai exclaimed.

The door opened and a flashlight clicked on, revealing the spiky-haired teen. "It's me, Mai," Yugi confirmed and began using the flashlight to stare around at his surroundings.

"But how in the world did you get here?" Bakura wanted to know.

"I'm not sure," Yugi replied. "I was in a long tunnel deep in a UFO. Somehow it led me here."

"A UFO?!" Bakura said in disbelief.

"Hey, I hate to ask, Yugi, but it wasn't you cackling like a maniac, was it?" Mai asked.

"It wasn't me," Yugi said, looking concerned.

"Then there must be someone else in here," Bakura said worriedly.

He couldn't have been more right. With another evil laugh, the headless phantom began to materialize in front of them. When it spotted Yami Bakura glaring at it, the monstrosity backed up, completely bowled over. "You should have been destroyed!" it said finally in its scratchy voice.

"Well, as you can see, I haven't been," Yami Bakura growled. "And now you shall pay for what you tried to do." He reached for his card deck.

"Wait!" Yugi said sternly. He turned to the phantom. "Tell us who you are," he requested.

"Your worst nightmare," it hissed in reply. "Now you will all perish!"
