Sâdo (1978)

In the Kanto Asahi juvie, which is marshy on three sides, the teenagers call the roll, clean, eat and work every day, leading a monotonous life. One of them, nicknamed "third baseman", used to be an excellent third baseman on the high school baseball team. The older Ming clashed with the "third baseman" and the two were locked up in a separate cubicle. Soon after, the mother of the third baseman came to visit, but he remained cold. SBC, a social welfare group, comes to juvie every three months, and only then can teenagers get in touch with young women. At this time, another teenager was sent to juvie and became the work partner of the "third baseman". His nickname was "2B". One day, a teenager nicknamed "Silence" managed to escape from the farm. The "2B" who couldn't stand the life inside also tried to escape, but was finally sent back. The "third baseman" beat "2B", but there was also a strong desire for freedom in his heart.
