"Promise me you'll look after Colleen and Greg" Romayne implored as she gasped for breath. "I promise you," Nathan said. He squeezed her hand gently. She tried to squeeze back, but couldn't. Then she died. And, for all intent and purpose, so did Nathan. Nathan O'Shaughnessy's life starts falling apart after his wife passes. His grandson, Greg, is killed by gang bangers and his granddaughter, Colleen, is traumatized. His daughter, Jill, is a drug addict. His loving cat, Gypsy, is murdered. One gang banger is killed by the other in a fit of rage. Nathan must stop the madness. Detective James Burton, who lost a partner to a gang banger in an alley in L.A., is determined justice will be served, one way or the other. Convinced Nathan and Burton are working too slowly, in the dead of night, Colleen confiscates her brother's car and proceeds to investigate on her own. Burton is staking out the killer's house and watches Colleen arrive, followed closely by Jill, with Nathan just minutes behind. A fight erupts between Colleen, her mother, and Jill's drug dealer. Burton intervenes and is killed. The killer runs, in an attempt to evade justice. Colleen, Nathan, and Jill are in hot pursuit, all determined that steel jacket justice will prevail.
