Rebekka, Claudia and Sofie are freshmen in high school and will no longer accept being treated as juniors. Taking matters into their own hands, they devise a rite of passage, the 'fortune teller', symbolizing their entry into adulthood. As they take turns challenging each other's sexual boundaries, they eventually have to ask themselves whether performing weird rituals is the easiest way to get to know themselves and feel grown up.

A dying elderly scientist proposes love-sick Jonas a cure that will improve the youngster's physical skills and general sex-appeal. What the scientist really aims to accomplish is a body switch: he wants to survive in a young man's body and gladly leaves Jonas to wake up in his own wasted frame. Jonas must somehow signal his predicament to his friends. Both men rev up for a survival-of-the-fittest chase.
