One Down, Two To Go (1982).
Set up by the mob, New Jersey fight promoters Ralph and Chuck are cheated out of the receipts of a martial arts tournament they organized. It seems the mob wants to muscle in and run the whole show. When Ralph and Chuck are beaten and shot to within an inch of their lives, they call in their hard-core, gun-toting buddies Carl and J to help even the score.
Directed by Fred “The Hammer” Williamson. Starring: Jim Brown, Fred Williamson, Jim Kelly & Richard Roundtree. (89 mins).
