2019: Julianne is preparing a family dinner when her son comes to her and says he's found something on his iPad. Something so terrible, it will turn Julianne's world into a nightmare and make her question everything about her marriage and what type of man her husband is or is pretending to be. 1990: Holly is a fresher student at Oxford University. Out of her depth and nervous about her surroundings, she falls into an uneasy friendship with a group of older students from the upper echelons of society and begins to develop feelings for one in particular. He's confident, quiet, attractive and seems to like her too. But as the year progresses, her friends' behaviour grows steadily more disconcerting and Holly begins to realise she might just be a disposable pawn in a very sinister game.
