With his boss in the madhouse, a mobster is temporary boss of the criminal empire just as vicious rivals threaten the control of the empire.

The Devil's 8 is a 1969 film from American International Pictures. It is about a Federal agent (Christopher George) who recruits six convicts to bust a moonshine ring.

Hooker and Gondorf pull a con on Macalinski, an especially nasty mob boss with the help of Veronica, a new grifter. They convince this new victim that Hooker is a somewhat dull boxer who is tired of taking dives for Gondorf. There is a ringer. Lonigan, their victim from the first movie, is setting them up to take the fall.
