Cagney & Lacey

Disenfranchised (aka Incest) (6x4)

Air date: Oct 27, 1986

(Also given to me as ""Incest."") A girl says that their father is molesting the younger daughter, who is too young to testify. How does she know? Because she was molested herself. Cagney and Lacey get the children away from their parents, but have to split up the girls to do so.
