London, 1953. Mr. Williams, a veteran civil servant, is an important cog within the city's bureaucracy as it struggles to rebuild in the aftermath of World War II. Buried under paperwork at the office and lonely at home, his life has long felt empty and meaningless. Then a devastating medical diagnosis forces him to take stock, and to try and grasp some fulfilment before it passes permanently beyond reach.
Having recently found God, self-effacing young nurse Maud arrives at a plush home to care for Amanda, a hedonistic dancer left frail from a chronic illness. When a chance encounter with a former colleague throws up hints of a dark past, it becomes clear there is more to sweet Maud than meets the eye.
