­To solve the brutal murder of a Navy officer-turned-peace worker, Hetty pays a visit to an unpredictable former colleague who the peace worker was working for. He appears to try and help our team to find the killer but we soon discover he lied to our victim, making her believe she was working to help rebuild parts of war torn Afghanistan but Hetty's former colleague hid his true money-making intentions behind a smoke-screen of philanthropy. Hetty confronts her old friend who now threatens to kill her when he feels cornered. Our team jumps into action to take him down, save Hetty and expose him for what he really is.
