On an inspection tour of the hospital, Professor Caroline Edgewater and her grand-daughter Phoebe are pleased to encounter Mitch, Caroline's former student and a friend to both of them. Mitch was a close friend of Caroline's daughter Sarah, who died of cancer when Phoebe was little and he was emotional support to all of them during the difficult months of her illness. Time and tyranny of distance have meant they have lost touch but Phoebe and Mitch quickly fall back in to their former affectionate, teasing relationship.
