Trainyard-man Jim finds a $30,000 necklace that was lost by young society matron Ruth Vaughn. Ignorant of his value, the man places it around the neck of his motherless 7-year-old daughter Nell. Jim falls ill. His savings vanish. Nell tries to nurse her father. Unable to secure money for medicine, the girl resolves to sell a potted plant that church workers gave her. She wanders far in her effort to dispose of the plant. When she pauses in front of a jewelry shop, the jeweler recognizes the Vaughn necklace and has one of his clerks follow Nell home. Mrs. Vaughn and the police are notified. Detectives enter Jim's miserable home and accuse him of having stolen the necklace, which they remove from Nell's throat. They are about to arrest him when Mrs. Vaughn enters. Taking in the situation at a glance, the woman orders Nell's father freed. Jim tells how he had found the jewels and of how Nell has taken care of him during his illness. Touched, Mrs. Vaughn takes the child under her own care while a brighter future dawns for Jim, who becomes Mrs. Vaughn's gardener.
