James is getting on a bit and needs full-time help. So Phoebe and Robert, his middle-aged offspring, employ Mandy, who seems willing to take him off their hands. But as James regales his family with tales of Mandy's virtues, Phoebe and Robert sense something is amiss. Then something extraordinary happens which throws everything into new relief, changing all the stories of their childhood - and the father - that they thought they knew so well. From the author of "The Best Exotic Marigold Hotel".
