Falling Flower Peanuts

Two mysterious tough guys, Ryuji Hoshikawa and Kyotaro Ochiai, win money at the track but have some of their winnings swindled by Tetsu, a member of the Hyakkikai posing as a car dealer. Mr. Makimura, an elderly fish seller, cannot pay off his debts to the Hyakkikai so he jumps in front of a car being driven by Ryuji and Kyotaro but they stop in time and help him by robbing a Hyakkikai gambling den and giving him most of the money in order to repay his debt.
