The Blue Knight

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.

Bumper tries to help the mistress of a sadistic crime lord, who has her beaten up when she tries to leave him, so he hooks up with vice cops who offer her protection if she will agree to testify against the man.
