Reaching his last week on the force before retirement, Bumper decides to devote his time to searching for a fellow officer's killer.
Two vicious hoodlums turn Bumper's district into a war zone when they start targeting their fellow lawbreakers, who can't go to the police for help after they are beaten and robbed.
After wounding a suspected mugger, Bumper tangles with the man's sister, a prominent attorney who refuses to believe that he is a criminal and wants to get Bumper's badge taken away.
