Croydon, 1964. Art therapist Helen Hansford is working in a psychiatric hospital, where she has been having passionate but precarious affair with her married colleague, the charismatic Dr Gil Rudden.Helen's structured life is upended when William Tapping - a silent, thirty-seven-year-old man with a beard down to his waist - arrives the hospital. As Helen helps William express himself through art, she becomes increasingly entangled in his mysterious past.

And repercussions are just what Guy doesn't need: his wife, Jane, is moving swiftly from slightly eccentric to downright peculiar, their three-year-old daughter seems set on destroying Jane's sanity, and now even God's gone quiet on him.As for Nina, she's having enough trouble with her son, James. He's got exams looming, a new girlfriend with pneumatic breasts and now, it seems, he's on drugs. Nina certainly won't welcome any ghosts from the past.

Then one day she encounters a face in the crowd which jolts her out of her mundane existence and makes her question both her life and the past that has helped to shape it. Memories she had long chosen to forget begin to resurface. Memories of an eccentric childhood in a large and shabby house, where the children were left to fend for themselves within the loose boundaries of their parents' unorthodox values. A chaotic existence peopled by a rich collection of feckless 'guests'.
