Still haunted by the death of her brother James seven years ago in World War I, Evelyn Gifford is shocked when a young nurse named Meredith and her six-year-old son appear on her London doorstep. Meredith claims the child is James's son, and the grief-stricken Evelyn welcomes them into her home.

At the same time Evelyn, a struggling attorney, is defending a veteran charged with murdering his wife. She believes her client is innocent, just as she suspects there is more to the story of her "nephew" than meets the eye.
