The "Cop Idol" Christmas party gets into full swing, with everyone blissfully unaware that Rickman is lying unconscious in the boot of a car. Stamp and Best find a man wandering the streets and take him home, only to find he is living alone and without electricity. They decide to delve into his financial situation, and discover that either his neighbour or the builder he employed, or both, have been ripping him off. A visit to Phil's old nick gives Klein enough ammunition to get Hunter off his back. Webb is gutted when Cryer's hunky date arrives, and Young's concern about Cass increases when Simon Kitson turns up looking for her. In a darkened warehouse, Rickman fears that she may succumb to the serial killer.
