Francis Hardy has an unusual job. He, his wife, Grace, and his loyal manager, Teddy, travel across the British Isles performing a series of almost vaudevillian faith healings. But like any professional, Hardy begins to worry about losing his talent, or whether or not he ever really had one. The strain is felt by his wife, observed by his manager, and so grips Francis that he becomes obsessed with curing the incurable, no matter the cost.
