Lloyd, now happily married, leaves the apartment of his old girlfriend after assuring her that there can be no future for them. Once down on the street he is shot to death during a botched mugging by a lone female. Capt. Grey's wife is a friend of Lloyd's wife, so he commits M Squad to the case. When Lt Ballinger speaks with the widow, she assures him that despite all the evidence to the contrary, her husband was completely faithful. However, police procedure says he must follow that lead. At the same time, he checks with the robbery section and learns that this was likely the tenth of comparable, but non-fatal, recent muggings. He immediately recalls a similar case from several years prior, thus a new trail to follow.
