A power pack of a movie as 4 'forces' come together to take vengeance on 'The Mob'. The Mob's mistake?... they've rigged the money spinning kung fu tournament that had been set up by Ralph (Richard Roundtree) and kung fu master Chuck (Jim Kelly) but events turn bloody as 'The Mob' increase the pressure on Ralph and Chuck. Shot, beaten and bloodied they need help. It's not long coming in the awesome shape of Cal (Fred Wiliiamson) and 'J' (Jim Brown). Together they form a 4pack solid fighting force intent on settling the score... they will be avenged and no prisoners will be taken!
