Noboru's gang punishes the domesticated sailor
In postwar Yokohama, thirteen-year-old Noboru watches his widowed mother Fusako and the merchant sailor Ryuji through a hole in his bedroom wall and worships Ryuji as a man bound for a glorious, solitary destiny at sea. When Ryuji gives up the sea to marry Fusako and help run her luxury goods shop, Noboru's gang of six boys, led by a cold nihilist they call the chief, judges this a betrayal of glory. The boys lure Ryuji to a hillside, give him drugged tea, and prepare to dissect him as they earlier dissected a kitten.
