Janet is unnerved to discover that Dodson can't ignore her concerns about Gill's drinking. And just as Rachel feels like she's on top of the job, she makes a fatal error that puts Janet and Chris in danger and makes Janet wonder whether their flirtatious behaviour meant she took her eye off the ball. A man's body is found wedged between rocks on the moors. With nothing to identify him, a road block is set up and an appeal put out. When enquiries lead Janet & Chris to a nearby farm, they discover something much more sinister and shocking than they could've anticipated.
