other actors are replaced by the projectionist's "real" acquaintances. The dream begins with the theft being committed by the villain with the aid of the butler. The girl's father calls for the world's greatest detective, and Sherlock Jr. arrives. Fearing that they will be caught, the villain and the butler attempt to kill Sherlock through several traps, poison, and an elaborate pool game with an exploding 13 ball. When these fail, the villain and butler try to escape. Sherlock Jr. tracks them down to a warehouse but is outnumbered by the gang to which the villain was selling the necklace. During the confrontation, Sherlock discovers that they have kidnapped the girl. With the help of his assistant, Gillette, Sherlock Jr. manages to save the girl, and after a car chase, manages to defeat the gang. When he awakens, the girl shows up to tell him that she and her father learned the identity of the real thief after she went to the pawn shop to see who actually pawned the pocket watch.
