Lt. Frank Harris, a tough plainclothes police officer, questions Joseph Spooner, a junkie informant, to try to break a case. After Harris drops Spooner off, he is beaten and killed by two hoods. Harris was the last person to see Spooner alive and the junkie's death sets off protests about police brutality. Erskine and Rhodes are called in to investigate before a volatile situation turns explosive.
