Young Timmy Turner was sitting in his room doing his best to avoid his evil babysitter Vicki. He was meant to work on a school project, but as usual was doing his best to distract himself. Currently Timmy was on his computer playing his favorite Crash Nebula videogame. Cosmo and Poof were inside his game as two playable characters that Timmy was controlling while Wanda was doing her best to get Timmy to work on his school project, not at all amused that her son and husband were enabling Timmy.
"Oh come on, I'll get to it eventually," Timmy said as he made Poof blast another alien.
Wanda rolled her eyes but decided it best to leave well enough alone, for now. Timmy's attention went back to the videogame, only something was happening that Timmy knew immediately was not part of the game. Cosmo and Poof, both of whom were dressed in space suits, were running away from a shadowy figure wearing a cloak. The man was floating towards them emitting a ghastly glow.
"Is that part of the game?" Wanda asked.
Timmy shook his head as Cosmo and Poof screamed for help. "I wish Cosmo and Poof were out of the videogame!" Timmy shouted. Just as the unknown man made to blast Cosmo and Poof they appeared next to Wanda, out of breath.
"Curses!" the figure shouted. "I will get out of this infernal excuse for entertainment, I promise you that! And you, Timmy Turner, will be the mighty Technus,' first victim!"
Quickly Timmy unplugged the computer turning to face his godparents. "Who was that?"
"I don't know Timmy," Wanda said. "But perhaps it's time you take a break from videogames for a while."
"Awww," Timmy and Cosmo said in unison. Wanda smiled with satisfaction.
Meanwhile in Amity Park, Danny Fenton found himself with his two best friends, Sam and Tucker, at his home working on a school assignment. "Ugh, I can't believe Mr. Lancer is making us do a five page book report on A Tale of Two Cities," Danny said as his head fell to his desk.
"Oh come on Danny," Sam said with a grin, "it's not that bad."
"Yeah, it could be worse," Tucker agreed. "Your father could have clumsily created some sort of device that lets out a whole horde of ghosts from the Ghost Zone."
Just then Danny's father, Jack Fenton, barged into his room. "Good news, Danny! I just invented the Fenton Ghost Nabber!" Danny looked to Tucker, shaking his head from side to side. "It's a new and improved version of the Fenton Thermos. Only one downside, though."
"That being?" Danny asked.
"Instead of nabbing ghosts it released all the ones that you had caught in your thermos," Jack sheepishly admitted.
"Thanks a lot, Tuck," Danny said. Tucker looked extremely guilty as he attempted to hide beneath his hat.
"How did your device release the ghosts that Danny caught, though?" Sam asked.
"I added on a special feature that syncs up the two devices, and I accidentally hit release," Jack said as he rubbed the back of his neck. "Just thought I'd let you know." Jack then left the room leaving Danny feeling even more depressed than before.
"You know, I'm not so sure my parents knowing about me being half-ghost is a good thing," Danny said.
"Come on, let's get down to the lab and see if we can track any of those loose ghosts," Sam said as she grabbed Danny and Tucker's hands and dragged them away.
Once the trio reached the basement they covered their ears due to a piercing wail. "That's not good," Tucker said.
"You can say that again," Danny shouted. "Especially since the Ecto-Exodus alarm is going off!"
At that moment Danny's parents barged into the basement. Danny's mother, Maddie Fenton, turned the alarm off and a screen lowered from the ceiling. "This is the biggest outbreak of ghosts into our world I've seen in quite some time." She looked between her son and husband. "What happened?"
After Jack explained his latest failure Maddie lowered her head. She then turned to Danny. "I'm so sorry, Danny. Me and your father will go and round up all the ghosts he let loose." She lowered her voice. "You know how your father can get." Jack looked chagrined at this comment and pretended not to have heard what she had said.
Danny then felt bad. "It's okay mom, it's nothing that me, Sam and Tucker can't handle."
Maddie looked to Danny with a smile. "I can't help but realize how responsible you've become."
"I've got you and dad to thank for that," Danny said. "If I hadn't gotten into that accident I never would have become a ghost in the first place."
"We can change you back you know," Maddie said for what seemed to Danny the millionth time.
"No mom, this is who I am," Danny said. "It's made me a better person."
"He's right," Sam agreed.
Maddie sighed. "If you kids insist."
While Danny had been talking with his mom his father had left the basement and went to the RV. It soon became apparent as to why. "That's odd," Maddie said tracing her finger along the map that had come down.
"What's that?" Danny asked.
"All but one of the ghosts are haunting some part of Amity Park," Maddie said.
"And the one that isn't?" Sam asked.
"It's ghost energy is off the map," Maddie said. She then snapped her fingers and an even bigger map appeared adjacent to the one that was already down. "It leads to a town called Dimmsdale."
The trio looked to one another. "Where is that?" they all asked together.
Maddie looked around and sighed. "Probably the exact place your father is heading to as we speak. A town in Northern California. I suppose I should go after him. Jazz is in charge while I'm gone." She then left the trio in the lab.
Sam and Tuck looked to Danny. "Well, what do we do?" Tucker asked.
Danny looked determined. "Well, we go to Dimmsdale." He looked to Sam and Tucker. "But we don't let my parents know that we're there."
"That's the Danny I know!" Sam said raising her fist in the air. The group then went upstairs to get ready for their trip.
