Night Feeder (1988)

Fear chokes the free-wheeling underbelly of San Francisco's punk scene as a killer stalks the night to feed an unspeakable appetite. Community suspicion focuses on Disease, a band that is tainted by groupie deaths allegedly induced by the drug DZS, and on "The Creeper" a misshapen outcast from the bowels of the city. A writer probes the gruesome murders and the story hits close to home, as the web of death devours neighbors, friends, and lovers.
