Set in the early 1920s, the film follows Tom Birkin, who has been employed to carry out restoration work on a Medieval mural discovered in a church in the small rural community of Oxgodby, Yorkshire. The escape to the idyllic countryside is cathartic for Birkin, haunted by his experiences in World War I. Birkin soon fits into the slow-paced life of the remote village, and over the course of the summer uncovering the painting begins to lose his trauma-induced stammer and tics.
