Candace rushed home with her mom to show her the ridiculous contraption that Phineas and Ferb had built in their backyard. It never worked but Candace refused to give up despite every single failure. Sure she kind of let it run her life and get in the way of spending time with Stacy and Jeremy but she didn't really care that much for some reason. At last they pulled into their driveway and Candace pushed her mother out of the car to see what Phineas and Ferb had built.

"Thanks, Vivian. See you Tuesday for totem pole carving.", said Linda as Candace pushed her into the front yard. Candace moves her mom into the front yard to see the giant launch pad the boys have built and to Candace's absolute shock she notices it and Phineas and Ferb fly by with a flying car that just so happens to be the family station wagon.

"PHINEAS AND FERB GET DOWN HERE THIS INSTANT!", Linda yelled and Phineas and Ferb obey. Linda begins to chew them out for modifying her car and building something ridiculously dangerous without her permission but Candace is still in shock that she had actually done it this time. "Holly shit!" she thought to herself silently. She snaps out of it when Phineas tells mom they do this type of stuff all the time. "See mom? I told you… but you never listened." said Candace as her mom recalls everything Candace ever told them about the boys. She immediately apologizes to Candace for not believing her and being so rude to her as Lawrence comes home and notices the launch pad and the car.

Lawrence tells Linda he did not now about this but agrees they should be punished. "Well, some punishment may be in order, but look, there's no harm done really.", replies Lawrence. Phineas then notices something on the ground and bends over to grab it. "Hey, look, Ferb, here's bolt number 473. I hope that wasn't important.", he says, and with that the tower begins to shake and rattle and eventually fall… right towards them!

"Get the hell out of the way!", yells Linda as the tower comes down. Ferb trips on a piece of metal and Phineas turns around to help him. Candace turns back around and screams "PHINEAS, FERB, LOOK OUT!". The two try to escape but the tower comes down on top of them. "NO!", Linda yelled. She, Candace, and Lawrence rushed over to the pile of rubble. Within the pile they find the unconscious bodies of Phineas and Ferb. Candace rushes inside to call 9-1-1 while Linda and Lawrence stay with boys, and as if on cue, Perry walks in. He immediately gasps, chatters loudly, and rushes over to Linda's side. "Phineas please, wake up, wake up.", she says with tears in her eyes as police and an ambulance arrive.
