Officer Ryotsu finds himself caught in an unlikely rivalry with an elderly woman during a high-speed train journey from Abashiri to Tokyo. What starts as a simple commute turns into an escalating battle of wills when the eccentric grandmother refuses to follow basic passenger etiquette, forcing our perpetually exasperated cop into increasingly absurd situations. The confined space of the speeding train becomes ground zero for their clash, with other passengers caught helplessly in the chaos. Ryotsu's attempts at maintaining order crumble against the woman's stubborn determination and unexpected tricks, leading to a comedy of errors that picks up speed right alongside the locomotive. The special captures the franchise's signature style of physical humor and character-driven chaos, where a simple premise spirals into complete mayhem. Perfect for viewers who thrive on slapstick comedy and appreciate protagonists pushed to their comedic limits by forces beyond their control. The humor lands best if you enjoy watching authority figures get thoroughly outsmarted by the most unlikely opponents.
