John, a repressed man, is shocked to find himself in middle age, secretly raging at his life as a stay-at-home dad. When his failure to intervene in a violent confrontation in a playground brings his identity crisis to a head, John ups and moves his family to the rural idyll of Coldwater, as far away from London as possible. Upon arrival, John is quickly befriended by next-door neighbour Tommy, a charming, confident man, devoted husband to the local vicar Rebecca. John is both impressed and slightly fascinated by Tommy whilst his wife Fiona despises him. When her husband’s relationship with their enigmatic new neighbour becomes increasingly intense, Fiona’s suspicions are aroused. She is unconvinced Tommy is all he seems to be, but John remains blissfully unaware that Tommy is harbouring horrifying secrets.
