Part 5 in a long running (8+1 films) action/comedy/melodrama series about a pair of short tempered, amoral, but not evil chinpira (Bunta Sugawara and Tamio Kawachi) thinking too big of themselves. After serving four and a half years in prison, Masa and his brother Katsuji leave Kobe to go to Nagoya to help a hostess get her daughter back from her mother. As they arrive in Nagoya, they get into a scuffle with the local yakuza affiliate. Sugawara and Kawaji's chemistry is even more evident here than usual, the storyline is alright if melodramatic. Delightful start with Tatsuo Endo as a nice guy prison guard! How many times have you seen that? And we got Kyosuke Machida (henchman) with cool beard and the always good Tsunehiko Watase (young hood) on board as well. One of the best films in the series.

Upon his release from prison, Masa (Bunta Sugawara) is disappointed to not be picked up by his brother Katsu (Tamio Kawaji). After hitching a ride on a bus full of old women, Masa finds out that Katsu tried to fake a car accident and get some money for Masa to live on after prison. Together, the two decide to blackmail the woman (Yoko Horikoshi) who hit Katsu, who happens to be the daughter of a rich company president (Seizaburo Kawazu). 6th film in a series of 8.

Part 7 in a long running (8+1 films) action/comedy/melodrama series about a pair of short tempered, amoral, but not evil chinpira (Bunta Sugawara and Tamio Kawachi) thinking too big of themselves. Katsuji finds his long lost mother, who is a rich lady of a respectable family. Comedy and melodrama ensue. A thrilling spectacle with an overly violent ending, and a remarkable, Japan's only post-prison rape comedy, Masa is determined to have sex with the female guard, despite the fact that there is a bar between them. Michi Azuma (topless swordswoman from Lone Wolf and Cub: Baby Cart in Peril) plays a tomboy who wants to join her brothers.

The last in the series. Sugawara runs into two mahjong cheaters (Ichiro Araki and Mako Midori + sidekick Takuzo Kawatani) whom he takes for friends in need as his naivety prevents him from seeing their true nature.
