I Was a Teenage Zombie

Six high school buddies accidentally kill a drug pusher and dump his body in toxic waters. When the pusher returns as a zombie and goes on a killing spree, their only recourse is to dump the body of one of their own recently dead, and have him return as a "good" zombie to face off with the "bad" one. The producer's hook for the film was to feature music by groups the likes of The Fleshtones and Los Lobos.
