While in Wales visiting her husband James (Sean Bean), Adélle (Maria Bello) tries to fix her relationship with her daughter Sarah (Sophie Stuckey). By the side of a cliff, they see a strange memorial with evidence of a plate missing and with the name "Annwyn" marked on it. A local man Dafydd (Maurice Roëves) explains that, according to traditional Welsh mythology, Annwyn is a sort of afterlife.
