Denny Burke is now going to graduate high school. Senior year has been one thing after the following: a broken leg and -- worst of all -- a broken home. With four of his closest friends, Denny goes on one last rock climbing trip to prove he is ready to start his mature life... On their trip the five adolescents get a genetic boost beyond anything they'd ever envisioned. Denny's soon faced with the very first big decision of his mature life: does he give these forces and stay the usual teenager, or does he retain them...and graduate from the human race?
