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.
Unfortunately the movie The Viper Brothers: Up on 30 Charges is not yet available on HBO Max.
