Filmed and set in Wales, Wolf is written by Megan Gallagher and based on Mo Hayder’s acclaimed Jack Caffery novels.

In an isolated house in the country a family find themselves the victims of a terrifying psychopath’s cruel games. Meanwhile DI Jack Caffery obsessively tries to find evidence to convict the neighbour he believes murdered his eight year-old brother in the 90s. When these two narratives collide it’s a race against time in this emotionally powerful, nail-biting and deeply disturbing crime-thriller/horror mash-up.
Wolf is Executive Produced by Ben Irving for the BBC, Elaine Cameron for Hartswood Films and Laurent Boissel for APC Studios.
Writer Megan Gallagher says: “Mo Hayder’s Wolf is a compelling, unique story with a bold, genre-mixing narrative. After reading the book in a single day, I knew I had a gem in my hands. I consider it an honour to bring DI Jack Caffery to BBC One, and working with the experienced, passionate producers at Hartswood and APC Studios is simply icing on the cake.”
