Piers Morgan continues his quest to discover what drives some women to kill. Travelling to Bedford Hills Correctional Facility in New York State he meets Sheila Davalloo, convicted for the murder of Anna Lisa Raymundo. In a bizarre twist, Sheila has yet to start the 50-year sentence she was given for this murder. First she has to complete the 25-year sentence she was given for the attempted murder of her husband. The murder may never have been solved had Sheila not decided to play a violent sex game with her husband - a game which involved handcuffs, a blindfold and a knife. Piers discovers that after stabbing her husband twice, Sheila drove him to hospital where she stabbed him a third time - this time nicking his heart. A sex game gone wrong had become attempted murder, and Sheila was arrested. It was only then that a connection was made between Sheila and Anna Lisa, as Anna Lisa's boyfriend was also Sheila's on-off lover.
