Cagney & Lacey

Mary Beth awaits a possible promotion, while Cagney turns to booze after her father's death.

With Christine busy looking for a missing child and getting ready for the sergeant's exam, Mary Beth prepares for her breast surgery.

In the fifth-season opener, Cagney, Lacey and Lieutenant Samuels are forced to investigate one of their own. It starts when a junkie's broad-daylight burglary makes him easy prey for Cagney and Lacey, who happen to be across the street at the time. What isn't easy to take is the tip the addict offers in a bid for leniency; he says he saw a cop pocket some heroin from a crime scene--a detective from their own 14th squad. Bypassing Internal Affairs, Chris and Mary Beth go to Lieutenant Samuels, who orders them to have the junkie ID the alleged felon--and it's a real shocker. Even more shocking is their suspect's behavior when they set a trap for him, a trap that could very well ensnare them all. (TV Guide)
