In this story set at a seaside fishing village and inspired by a Charles Kingsley poem, a young couple's happy life is turned about by an accident. The husband, although saved from drowning, loses his memory. A child is on the way, and soon a daughter is born to his wife. We watch the passage of time, as his daughter matures and his wife ages.
