Craving Pleasure: Attack a Virgin (1981)

A man who was a radical student activist during the 1970 Security Treaty protests was arrested by the police and worked as a bartender in a rundown bar after being released from prison. The failure of the student movement had eaten away at his mind, and he lived a self-indulgent life living with a woman. Meanwhile, his father, an elderly fisherman, and his sister still lived in his hometown, but the sea there was polluted by wastewater discharged from a large company's factory, and the fish caught in the sea were poisoned, leaving many who ate the fish virtually disabled. In fact, his sister was also a victim, and her brain and nerves were so damaged that it was impossible to tell who was who. One day, the woman he was living with told him that she was pregnant. The man, who feels despair towards society, is unable to accept this reality...
