Violinist Alfred Wantez bids his wife Olga and son Billy farewell and embarks on a concert tour. On the way to the train he's attacked by a tramp who knocks him senseless, steals his clothes, dons them, and boards the train. The train is wrecked and the tramp is buried as the dead musician; Olga receives word of her loss. Meanwhile, the violinist has been discovered and carried to a hospital. On his recovery from his injuries, his memory remains a blank. Several years later an itinerant musician wanders into a seashore community, where Dr. Allen, who has taken a strong interest in the widowed mother and her boy, has sent them. The children follow the violinist. Billy tags along with the rest. The strains of "Hearts and Flowers" bring Mrs. Wantez out of her cottage. She sees Billy and his father walking hand in hand at the head of the little procession. The first shock of joy fades into bewildered sorrow, when she finds that her husband has no memory of either her or his son. Dr. Allen performs an operation upon Wantez's brain and he is restored, sane and happy, to his wife and son.
