Part one of two. Spoof crime drama by Charlie Brooker about DCI Jack Cloth (John Hannah), a maverick, alcoholic, widowed detective, and his incompetent partner DC Anne Oldman (Suranne Jones), who is redeemed only by her taste in personalised ringtones. The pair investigate a series of gruesome murders, and are assisted by foul-mouthed pathologist Natasha Sachet (Daisy Beaumont) and results-obsessed chief Tom Boss (Julian Rhind-Tutt)
