When a headless and handless body is found in a North London scrapyard, the team led by Sunny are called to investigate. They suspect the body was illegally dumped, perhaps transported inside a white goods item. This is confirmed when pathologist Leanne Balcombe finds that the dismembered corpse had been frozen. The body is identified as one Matthew Walsh who went missing 30 years before and we start to meet four people who may be connected with his disappearance.
