Bonnie Bedelia - in the triumphant performance that earned her a Golden Globe® nomination as Best Actress - stars as Shirley "Cha Cha" Muldowney, the young wife and mother who defied the sport of drag racing to become the only female top fuel champion in NHRA® history. But before she could reach the record books, Shirley had to survive an abusive first marriage, her volatile love affair with fellow racer Connie Kalitta (Beau Bridges), a horrific accident, and a sexist world that tried to stand in the way of one remarkable woman who dared to put her heart on the line.
