Fujun na seifuku: Modaeta futomomo (2008)

On the day of her graduation ceremony, Hiroko, a high school student, robbed an office with a gun in her hand after having a commemorative cover-up at a love hotel. She wanted to break out of her boring life. The man she went with was her childhood friend Hanamaru, a hoodlum. Hanamaru was reluctant to go along, but he was in love with Hiroko, so he took a part in the robbery. Before the robbery, they hooked up with Saki, a married woman, and added her to their gang. After paying Saki to keep quiet, they headed for the Sea of Japan. Shinichi, the older brother of the two and a member of the gang, served as a bullet and is now behind bars. Hiroko has a letter from Shinichi to give to his girlfriend, Hiromi, who lives in a town on the Sea of Japan. Meanwhile, Hideshi and Tamao, known among the yakuza as the "live kidnappers," were in pursuit of them. The two gathered information along the lines of someone who had paid off all their debts at once, approached Saki, and tracked down Hiroko and the others..
