DCI Jessica James and DI Sunil 'Sunny' Khan are back on the case when suspected human remains are discovered on Whitney Marsh. It soon becomes clear that the remains are relatively recent, and that the body was put there already dismembered.

Jess, Sunny and their team must unravel their connections to find out the truth.
