There's a growing epidemic among the kids at Santa Bella High: marijuana cigarettes. When slang-talking hipster Tony Baker (Russ Tamblyn) transfers to the school, he noses out the action right away, finding a connection in hotshot J.I. Coleridge (John Drew Barrymore).

But are Tony's motives really what they seem?
