Alan Bennett's story is based on the true story of Miss Shepherd (played by a magnificent Maggie Smith), a woman of uncertain origins who "temporarily" parked her van in Bennett's London driveway and proceeded to live there for 15 years. What begins as a begrudged favor becomes a relationship that will change both their lives. Filmed on the street and in the house where Bennett and Miss Shepherd lived all those years, acclaimed director Nicholas Hytner reunites with iconic writer Alan Bennett (The Madness of King George, The History Boys) to bring this rare and touching portrait to the screen.
