The misadventures of middle-aged cop Kankichi Ryotsu.
Officer Ryotsu is ordered to team up with FBI agent Lisa Hoshino to find a terrorist who is currently in Tokyo. For an unknown reason, only buildings from the Shinatora corporation seem to be targeted by the mysterious Benten.
The movie starts off with Ryotsu (with Honda as his patsy) hatching another crackpot scam with a fake UFO sighting (via fake crop circles and a wire-hanging UFO). But the plan fails per usual, with the Kameari Park Police Box which results in Ohara punishes Ryotsu by subtracting him from the station's group vacation to Hawaii the following day.
Kankichi Ryotsu is sulking after his bonus was snatched away by the members of the shopping district. On TV, they hear that Princess Sabrina of the Attakaino Kingdom is coming to Japan. While making a delivery, Ryotsu encounters a kidnapping incident. The girl he rescues from the kidnapper is Princess Sabrina! The kidnapping case develops into a major commotion that involves the downtown area! Will Ryotsu be able to protect the downtown area and everyone there?
