Series One

In the first series, D.I. Viv Deering is introduced as the dynamic but blunt leader of a team of detectives at a fictional police station within the 'Manchester Metropolitan Police'. D.C. Dinah Kowalska misses out on promotion to D.S. after leaving the scene after an impetuous foot chase results in a death. She then uncovers a link between a murder, a drowning and a disappearance: someone is killing girls with Down syndrome. While negotiating different cases, the team must solve the case as more girls come into danger. The prime suspect is killed whilst fleeing arrest, but Dinah and Viv separately conclude that Viv's husband is also involved. Viv burns the evidence and plans to kill rather than arrest him, but he is killed by Cathy whilst she and Dinah are holding him at Viv's home. With Viv they cover up their involvement before the body is found.
