Murphys Law [Charles Bronson]

Jack Murphy is a tough, antisocial cop. Things are not good for him right now; he just killed the brother of a mobster, and is now marked for death. His wife left him and is now an exotic dancer, and is trying to get her to come back to him and when she shuns him, he drowns his sorrows in the bottle. And if that isn't enough, it seems like someone is stalking him but before going after him, this person wants to torment him first. And what this person does is kill his wife and frame him. Murphy would be arrested and is handcuffed to a young street kid, whom he arrested earlier. They escape and Murphy tries to find out who did this to him.
