West Midlands Police are called after staff working in a tip yard make a grisly discovery: a decomposing body in a freezer which has been brought in for disposal following a flat clearance. A forensics team attends the scene, and the body and freezer are both removed for forensic tests.

The team must first identify the body, a process that eventually leads the police to a surprising discovery: one of the deceased's friends has known about his death for quite some time. Show less
