The detective's daughter is saved from a footpad by a passing stranger, and the acquaintance thus unconventionally begun deepens into love. One day she takes a snapshot of him and shyly shows the result to her father. She is dazed when the detective forbids her to continue the association, because the man has served a term for theft. He tells her sufficient of the story to prove that he is not mistaken. That night burglars break into the house, and one of them is wounded by the detective's pistol shot. The girl and her lover, who have met secretly outside, rush in at sound of the shot, and the man recognizes in the captured burglar his old office mate. The latter, impelled by conscience, relates how he ingeniously committed the theft and placed the blame on an innocent man.
