Sim and Walker find themselves investigating their third reported rape case in little under two weeks, but are shocked when the victim identifies Stamp as her attacker. Stamp makes no denial of trying to help the girl after finding her in distress, but thanks to interference from Smithy, Walker manages to help the girl gather some idea of her timeline, which puts Stamp in the clear. Walker then decides to mount an undercover operation in the hope of catching the attacker. Meanwhile, Manson investigates a dodgy medium who claims to have had visions of Amy Tennant - but first must work out how she managed to steal a doll belonging to Amy from her bedroom and plant it in the woods.
