While Mrs. Ray is getting supper for her pet cat it disappears. She calls up Burstup Homes, the detective, who comes to Mrs. Ray’s apartment and examines the rooms. He examines the cat’s paw prints, finds cat’s hair and a piece of music entitled “And the Cat Came Back.” These he considers invaluable clues. On the floor below he finds a man playing “And the Cat Came Back.” This suspect offers a connecting link in his chain of evidence and so he lassos him and after tying up the musician, he proceeds to secure further evidence. He continues on his way through the building and arrests many persons on trivial clues. Finally Burstup reaches the basement, where he finds four crooks, three men and a woman, quarreling about a fur piece. Burstup sees the fur and thinks it is the cat’s skin, appropriates it and arrests the crooks and drags them along with his other suspects to the police station. In the meantime, Mrs. Ray’s cat comes back and she goes to the police station and advises Burstup, and all the prisoners are consequently discharged by the judge and Burstup leaves amidst jeers.
