Adapted for television by Freddy Syborn from the novel by Daniel Cole, the six-part "Ragdoll" is described as a modern-day Faustian thriller. It centers on the murder of six people whose bodies have been dismembered and sewn into the shape of one grotesque body — nicknamed 'The Ragdoll'.

Assigned to the shocking case are DS Nathan Rose (Henry Lloyd-Hughes), recently reinstated to the London Met; his best friend and boss, DI Emily Baxter (Thalissa Teixeira); and the unit’s new recruit, DC Lake Edmunds (Lucy Hale). The 'Ragdoll Killer' taunts the police by sending them a list of his next victims, with Rose's name at the very end. With the victims to protect, our heroes soon come under intense public scrutiny. A gruesomely imaginative serial killer thriller, Ragdoll also captures the fascinating but flawed friends struggling with the consequences of institutionalization and trauma.
