Ruth Wilson (The Affair, Jane Eyre) stars in this drama inspired by her grandmother's memoir. Alison Wilson thinks she is happily married until her husband Alec (Iain Glen, Game of Thrones) dies, and another woman claims to be Alec’s wife. Alison is determined to prove the validity of her own marriage – but is instead led into a world of disturbing secrets.
As Alison Wilson continues to learn more about the fictions of her deceased husband, she loses track of what and who to believe. What was Alec's life actually like, how can she ever maintain faith in him – and how much should she tell her sons?
