Life is good for Gunn (Jim Brown). Not only does he live in a huge Los Angeles mansion with his beautiful girlfriend (Brenda Sykes), he's also converted it into one of the most most happening clubs in the city. But life isn't as good for his little brother, Scotty, a troubled Vietnam vet involved with a group of black militants. When Scotty and the radicals rob a gambling parlor owned by the mob, the gangsters strike back, and Scotty ends up dead. Now Gunn is out for revenge.
