Ryo is left with 150 yen every month after using his salary to pay off his debts.

A new recruit is starting at the police box today, going by the name of Keiichi Nakagawa. He is the rich heir to the Nakagawa corporation, and as such he wears a custom-made designer-brand uniform. He also collects guns and is shown to be a fan of American action movies like Dirty Harry. For his first task as a police officer, him and Ryotsu attempt to give an old man directions to a restaurant. However, this man can't recall what the name of the place is, only having a drawing he drew in elementary school as a clue. On top of this, the man has a flight to catch in a few hours, so time is limited. Will Ryo and Nakagawa be able to find the restaurant in time, and if they do, will it live up to the old man's memories?

Ryotsu decides to open a mobile convenience store by hot air balloon, which the police marks it an illegal operation.
