Synopsis: It's 1935. The headlines scream "murder most foul." All England is boiling with fury - scandalized by "the crime of the decade." Cause Celebre is an emotionally complex real-life drama of love, betrayal, guilt and obsession spun hopelessly out of control. Did Alma Rattenbury (Helen Mirren) - as she confessed - bludgeon her ailing husband to death? Or, was it Bowen, her 18-year-old lover - desperately driven by their affair into a fit of jealous rage?
