Bone is a punked-out teenager, living in a trailer with his alcoholic mother and abusive stepfather. Rejected by his parents, out of school and in trouble with the police, he's now into drugs and shoplifting as he drifts through dope squats and shopping malls. Until, breaking away from a group of biker thieves, he finds refuge in an abandoned school bus with I-Man, an exiled Rastafarian who dramatically changes his life.
