David Tennant (Doctor Who, Broadchurch) and Cush Jumbo (The Good Fight, The Good Wife) lead 'terrific performances across the board' in this 'complex and fascinating mystery' (Radio Times, UK).
Respected physician Tom (Tennant) and his schoolteacher wife, Kate (Anna Madeley, Patrick Melrose), have a seemingly perfect life in their small Scottish community with their best friends, Jess (Jumbo) and Steve (Matthew McNulty, Versailles). Until one night, when a fire ravages Tom and Kate's home, and Steve makes a disturbing discovery while attempting to save them. With evidence building that the fire was deliberate and perpetrated by a local, mistrust and suspicion begin to tear the town apart, forcing Jess and Steve to question everything they know about their friends.
