A Sting in the Tail(1989)

Diane Lane is intelligent and ambitious. When she is elected to Parliament her idealism and commitment give her unpopular party a boost. Everyone, including the Prime Minister, is eager to share her limelight. Diane’s ambition is not satisfied with her new position. Diane’s married lover, Barry Robbins, the Minister for Health, is unaware of Diane’s ultimate plan. Her closest friend, Louise Parker, a political journalist, is a bit more realistic about what women can achieve; she too has a higher goal in mind.
