Matlock (1986)

Season 9: Episode 11

Katie Clark is a hot new prosecutor in town, fresh from St. Louis, but originally from Atlanta. Her first case involves prosecuting a building contractor who has been accused of murdering one of his employees, who just happens to be Clark's former lover. Despite his reservations about Clark prosecuting a former lover, Matlock agrees to let her continue on the case, impressed by her desire to not allow her personal past with Gibson to affect her judgment.
