All Norman Hopper (John Saxon) wants to do is forget his tour in Vietnam. But when two fellow vets (Giovanni Lombardo Radice and Tony King) show up on his doorstep, the horrific memories return … and what's worse, the virus that made the trio crave human flesh soon resurfaces. Will the men be able to overcome it a second time? Italian director Antonio Margheriti helmed and co-wrote this cult classic during the late-1970s cannibal film craze.
