Bill, Mary, Gwen, and Jimmy are all swell kids. They listen to their parents, do well in school, and help out around the community -- that is, until they get caught up in the marijuana subculture. With "Mary Jane" filling their lungs, these kids resort to theft, prostitution, and murder to satisfy their cravings, which leads to suicide and death sentences. Is one puff really too much? A hilarious send-up of the 1936 exploitation film, now a cult classic.
