On a clear, crisp summer's day in Cornwall, a young man carefully prepares to take his own life, and asks family friend, Barnaby Johnson, to pray with him. Barnaby - priest, husband and father - has always tried to do good, though life hasn't always been rosy. Lenny's request poses problems, not just for Barnaby, but for his wife and family, and the wider community, as the secrets of the past push themselves forcefully into the present for all to see.
