The drama, set in a fictional town in Cheshire, begins with the brutal murder of a female GP in a busy children’s playground.

Detectives working to solve the case are quickly drawn into the twists and turns of a dark mystery, which takes them unexpectedly across Europe.

The trailer hints at a psychopathic suspect, multiple murders and mind games, as well as a complicated love story and family tensions.

Indira Varma, Robert Glenister, Neil Stuke, Lesley Sharp and Kevin Doyle star in the series. It was written by Bill Gallagher, who also penned The Paradise and Lark Rise to Candleford.

“Bill has written some incredibly well-defined characters who embark on a terrifying murder investigation,” said ITV’s Director of Drama, Steve November, who commissioned the programme.

“It becomes evident from the outset that malevolent forces are at play,” he said.
