Back in 1986, Justin Schumacher and his friends were just kids, but they were good breakdancers. During a contest against Kip Unger and his crew, and hoping to impress young Jennifer Stone, Justin tried a dangerous move, fell off the stage, and ended up in a coma that lasted twenty years.
Luckily for him, just when his parents -- Marty (CHRISTOPHER McDONALD) and Sylvia (DEBRA JO RUPP) -- have decided to "pull the plug," Justin (JAMIE KENNEDY) hears some retro music that snaps him out of the coma. Thinking he's still a kid but now in an adult's body and unaware of the cultural and technological changes that have taken place over the past two decades, Justin finds himself a fish out of water.
Learning that his parents are going to lose their home due to his high medical expenses, and wanting to win dance instructor Jennifer (MARIA MENOUNOS) back from dance promoter Kip (MICHAEL ROSENBAUM), Justin reunites the rest of his breakdancing squad -- Darnell Jackson (MIGUEL A. NUNEZ JR.), Aki Terasaki (BOBBY LEE) and Hector Jimenez (ARIS ALVARADO).
Aware of Kip's dance-off competition where the winning purse is $100,000, Justin wants them to compete, but his childhood friends are now early middle-aged men who haven't done any breakdancing for decades. Nevertheless, and as they try to bring him up to speed on all that he's missed -- including how to date women -- Justin hopes not only to win the contest, but also Jennifer's heart, all within the mindset of the kid he still thinks he is.
