Noodles wants to be an official member of the police department more than anything. But the rules won't allow cats on the squad, even if Noodles is the best rat-chaser in the city. Still, Noodles goes out every night and patrols the streets. One night he comes upon a pack of rats that are up to no good. While chewing wires the rats start a fire in a basement. Noodles gets into the house and wakes the sleeping children. The whole family escapes and Noodles is a hero. But, wait—Truman, the police dog with the K-9 unit, gets the credit. Will the rescued family set the record straight?
