Malloy and Reed have a monotonous day interrupted by two rambunctious female felonious joyriders, an exceptionally bright young boy with a photographic memory named Harold that clues them into a home burglary ring disguised as movers, respond to two paint-sniffing country bumpkins shooting rifles at a suspended box of dynamite, and check out a beauty school client who lodges a potentially explosive complaint. While at the station, Malloy and Reed decide to check in on Harold to discover he doesn't see the burglar's mugshot in the books. When they give Harold a ride home, Harold spots the burglar. Malloy and Reed make a successful, albeit bullet riddled, arrest and solve the crime while proving Harold's brilliance to the police department's doubting detectives.
