When a man is found dead and completely naked after bleeding out from a stab wound to his thigh, Bedfordshire's Major Crime unit charge two women who they believe enticed the man into meeting them with the promise of sex, but instead had the intention of robbing him. CCTV reveals the women were accompanied by two men on the night of the murder. Now with four suspects in custody, investigators need to work out who is behind the `honey trap" plot and which of their suspects is responsible for the murder.
