Without Motive is a British crime drama series broadcast on ITV, starring Ross Kemp as the protagonist, Detective Constable Jack Mowbray, a born and bred Bristol detective whose world is turned upside down when he is assigned to a major murder enquiry involving a serial killer, who is randomly attacking young women, apparently without motive.
[1] Detective Constable Jack Mowbray (Ross Kemp) investigates when the brutal murder of a young woman in Bristol sets off a chain of events, which, unbeknown to him, threaten to tear his family apart and change the course of his life forever.
With little clue or pattern to suggest the identity of the killer, the team are forced to a race against time to find the predator before he strikes again – without apparent motive.
Chapman's team also consists of WPC Margaret Walkinshaw (Jane Hazlegrove), a rookie officer barely out of her probation period, and DCs Mickey Lloyd (David Kennedy) and Phil Leighton (William Bateman).
Henderson's main adversary, Detective Chief Superintendent Huw Owen (Robert Blythe), is the initial investigating officer on the case.
