The Viper Brothers: Up on 30 Charges

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.
