After killing the Prof, Benton goes in search of his moll Eva (Marian Carr), and his old gang. The latter he kills in his single minded pursuit of revenge. While Police Lieutenant Chasen (Mac Showalter) ...er.. chases down the gang (that name surely has to be an in-joke?), the police begin a search for Benton. Unfortunately, as bullets don't work on Benton, they come armed with bazookas and flamethrowers!
It is all a lot of nonsense but pretty entertaining. The film is pretty dark and violent as well as ridiculous. It is basically a noir crime drama with a supernatural/monster addition and pretty enjoyable.
