The Totally Invincible Gentsuki Obasan!.An elderly woman, known as the 50 C.C. Old Lady, contravenes every traffic law in order to go after discounts and sale events in various department stores. Concurrently, the precinct is under siege as a rash of motor scooter thefts keeps the traffic division busy. Ken attempts to confidently pursue the 50 C.C. Old Lady, only to end in failure. She later comes to the precinct in tears, expounding that her supposed scooter was hijacking, which, consequentially, urges Natsumi and Miyuki to search for it. They go to numerous stores, but the 50 C.C. Old Lady becomes distracted by all the abated items. They eventually find two men riding in a van responsible for the thefts, witnessing the scooter of the 50 C.C. Old Lady being stolen. She manages to infiltrate the van and get back her scooter, continuing her habitual shopping sprees and traffic transgressions as usual.
