Spider Dale, a crook, while passing a factory sees Anne, one of the girls employed there, insulted by a foreman. He assists her out of her difficulty and wins her friendship. A moment later he sees approaching Officer Weldon, plain clothesman, and instinctively beats a hasty retreat. Officer Weldon is in love with the little factory girl, who has been protected from insult by Spider Dale, and he is at this time coming to meet her. Later Weldon receives orders from his chief to round up Spider Dale's gang, including Spider Dale himself, who is much wanted. Spider Dale and his fellow crooks plan and execute a raid upon a safe. Weldon and his men besiege the gang's headquarters, but the crooks escape. Spider is wounded in the arm. He stops for a moment in the doorway of a cheap apartment house and to his surprise, meets Anne. She sees that he is wounded and, without asking questions, invites him up to her room in order that she may dress his wounds. Before pursuing the chase further, Officer Weldon decides to call upon his sweetheart. She conceals Spider. Weldon enters and is not long in discovering blood stains. He questions the girl, but she refuses to answer. He leaves, but returns later with an officer. This time they catch Spider and the girl together. Weldon would have allowed Spider to escape when he hears his sweetheart's story, but the one great obstacle is, that with the reward offered for Dale, he and the girl had planned to be married. The arrival of his fellow officers cuts short his thoughts and he is obliged to turn the crook over for arrest. Anne realizes her sweetheart's position in the matter and forgives him. They are happily married, and upon Spider's release, Weldon hunts him out and invites him home to supper.
