Mike and Dave, two Northern British idiots sponging off the state, find themselves drunk with a case load of cash and the vague memory of a dodgy job offer. But when the sinister Mr. Martin comes to check his 'task' has been completed, Mike and Dave must learn to tell the truth or be lost in a lie forever.

Sophie is a troubled young girl, haunted by the abuse she suffered as a child and harbouring a deep fascination with the unexplained. In the hope of satiating her obsession with the latter, she instigates a trip to the Welsh countryside with four friends, aimed at tracking down the legendary Beast of Bodmin. It seems the mythical creature – often thought to be a large wildcat or fox – has caught the public's attention once more thanks to a spate of attacks on livestock and one local farmer. Armed with a video camera and a case of beer, the group head off into the woods but they soon uncover much more than they bargained for, with Sophie falling foul of a mysterious madman who locks her away in an apparent attempt to protect her from some unnamed terror.

Set during the 1960s in the fictional North Yorkshire village of Aidensfield, this enduringly popular series interweaves crime and medical storylines.
