Aliens land in the mythical town of "Speelburgh, U.S.A" searching for the source of rock & roll. What they find is a gang of teenagers, led by Dee Dee and Frankie, along with Frankie's posse/rock band, the Pack.

The pert Tina is sick of school and the muff in her Bavarian village. She wants to go with Tino - attendant of a visiting auto-scooter - who has to leave the place for dubious reasons. However he lets her down and leaves alone. Now Tina persuades fellow student Robby, who has a crush on her, to take her on a random trip with his motor-scooter. It seems only to be a matter of time until he realizes that she's just using him to follow her boyfriend - or will the shy Robby manage to win her heart on their chaotic journey?
