Here's the "dramatis personae" of The Fever. Bill Hunter is Jack Welles, an ex-cop turned unscrupulous private eye. Mary Regan plays his faithless wife Leanne and Gary Sweet is Leanne's lover, who schemes to bump off Jack. The "maguffin" in the case is a satchel full of illegal drugs. Little dialogue is spoken in the course of the story; still, the characters' actions speak volumes. The Fever is one of the most startlingly original films noir to come down the pike since the 1940s.
