Ryoutsu, being an underpayed policeman, is always coming up with ways to make some quick money. But in the end, his plans which are ridiculous from the beginning always go wrong and land him in big trouble.

Ryotsu Kankichi, nicknamed Ryo-san, is a senior patrol officer working at the Kamearikoen-mae police box at Katsushika. Because of his daring, hearty, unconventional, haughty and overbearing personality, he is called "letter of apology Ryo-san" and everything he does is nonsense. There is endless trouble wherever Ryo-san goes. He makes Akimoto Catherine Reiko and Nakagawa Keiichi, his juniors from the same police box, fearful. His superior, Ohara-buchou, lives each day as if lightning will strike as a fearless power keeps going off day after day. He definitely doesn't have poor ability as a "patrolman of the police box" in the mediation of quarrels, taking care of New Year's gifts or discussion of neighbourhood problems but he has a bad temper, gets tired of things easily and detests working. He is a police officer but because he loves gambling, he spends his money recklessly and in addition to this mess, is heavily in debt. He has a weakness for get rich quick schemes, and has a manic desire and knowledge to have fun and make money. Then one day, Ryo-san receives a tempting proposition...

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.

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?

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.

Police Officer Kankichi Ryotsu (Shingo Katori) is back at the Kameari Park Polic Box. Kankichi Ryotsu usually means to do well, but more often than not he ends up causing all kinds of trouble. Like on his way to work he away when he is asked to pay up by a shop owner or cheats an elementary school student. Ryotsu's co-workers Reiko Catherine Akimoto (Karina) and Keiichi Nagakawa (Mokomichi Hayami) have had about all they can take from Kankichi and his boss Ohara (Masato Ibu) is constantly berating him.
