The unsolved 1968 murder of a policeman is reinvestigated when a dying inmate claims he took a brick of heroin from the slain officer's patrol car shortly after the victim was gunned down in the same vehicle. The probe reveals the cop put the heat on a neighborhood drug dealer who had other officers on his payroll. The victim also had a reputation as a womanizer.
