Meanwhile, Sam and Alex have taken the hover/sub underwater to the Golden Gate Bridge.
"Search each support stanchion, Alex! We're looking for anything unusual."
"Right, Sammy!" says Alex.
Alex searches the first stanchion with the detecto-scan binoculars.
"Nothing here, Sammy. Everything looks normal."
"OK, let's check the next one then."
As the hover/sub leaves the first stanchion, a tunneling drone sticks its head out of the murky bottom, makes sure that the gals are headed away from it, and places a large explosive charge at the base of the stanchion. It does that for all of the stanchions, always waiting for Sam and Alex to complete their investigation first.
"I didn't see anything, Sammy!" says Alex after checking the last stanchion.
"I know, Alex! And the sub's scans didn't pick up anything either!"
Back at WOOHP, Clover is trying to dig up information on Mandy, to pass the time away.
"Hmmmm! Some parking and speeding tickets, nothing incriminating there! I have a goodly collection of those myself! I wonder if there are any cosmetic secrets...."
All of the sudden she hears a beeping coming from the laptop! She remembers Jerry telling her that if a beeping starts coming from the laptop, it means there are explosives near the hover sub!
Clover uses her compowder, "Sam! Alex! Someone has put a bomb close to you!"
"Are you sure, Clover?" asks Sam, as they finish the last stanchion. "We just checked all the stanchions, and came up empty!"
"Well, the trouble-alert says there is, so why don't you double check!" says a very concerned Clover.
As Sam turns the hover/sub back to the last stanchion, she sees the tunneling drone starting to exit.
"Oh, what's this?" asks Sam.
"I'm going to shoot a homing device onto it, just in case!" says Alex.
"Good idea!"
Alex scores a direct hit on the tunneling drone, using the sub's torpedo tube.
As Sam and Alex reinvestigate the stanchion, they now find the explosive device!
"That wasn't there just a few minutes ago!" says Alex.
"I know, but it's there now! We have to collect it, and deactivate it!" says Sam.
Sam slowly maneuvers the hover/sub close, so Alex can carefully recover the bomb using the subs remote control arms.
"Easy does it, Alex!" say Sam. She doesn't want to agitate Alex in any way as she knows any type of sudden movement could activate the bomb, so she is being quietly encouraging.
Alex brings the bomb on board slowly. "I'd better send this picture and the analysis scan to Clover.
"Clover?"
"Yes, Alex?"
"I'm sending you a scan of the bomb. You have to tell us how to deactivate it!"
"ME? I don't know anything about bombs!" says Clover frantically.
"Well then, ask Jerry!"
"He's having a tooth pulled and isn't here!"
"Then you're going to have to learn fast, Clover! We can't wait!" says Sam.
"OK!" says Clover as she starts frantically searching the various databases for bombs.
While they await Clover's research, Sam and Alex re-inspect the other stanchions, and find bombs by all of them. They end up recovering eight! They have also kept an eye out for the tunneling drone, but it hasn't reappeared. They recheck the stanchions a third time, and this time they are clear. They move the hover/sub about 5 miles away from the bridge, in open ocean. If the disarming doesn't work, at least no one else will be hurt and no damage will be done to any infrastructure! Sam and Alex start to do a preliminary examination of the bombs.
Finally, Clover calls back "Guys? Guys! I think I have it. These bombs are triggered by remote control! But if you try to deactivate them, they explode immediately!!"
On hearing this, Sam and Alex stop dead in their tracks. They decide the safest way to dispose of these bombs is to dump them into deep water, which they do. They have just finished this, and are about 2 nautical miles away when the bombs go off!!!
Clover hears the loud explosion over her compowder!
"SAM! ALEX!! Say something!!!!!" says a frantic Clover over her compowder.
After a few seconds, which seems like an eternity to Clover, Sam replies, "How about 'That was a close one'?"
Alex adds, "Or 'That job was the bomb'?"
"Very funny, you two! I am glad you're safe!" says a relieved Clover.
"So are we. But we need you to trace our homing beacon on that tunneling drone now, so we can go after the perpetrators," says Sam.
"Yeah! We have to find out who's behind this," says Alex.
"I am getting a reading.....I am sending the coordinates to your compowder. While your in route, I am going to see if there are any computer controlled systems I can break into at the destination," says Clover.
"Great Clover! We're on our way!" says Sam.
