In a fishing town by the Seto Sea, a student discovers a woman motionless on the beach and takes her back to his family's inn to nurse her, but he soon discovers than she is an extremist on the run from the police.
The story of an orphan girl, brought up in naive, rustic innocence by an elderly relative, who is suddenly exposed to the brutality, greed and deceptiveness of the outside world when her grandmother dies. Notwithstanding her healthy distrust of all strangers, which her upbringing instilled in her, it is not long before a cunning racketeer finds her weak point, that temptation which she cannot resist, that weakness, different as it may be, that each of us has, and brings her into his power. What follows is a depiction of her cruel descent into the depths of moral decay, as she becomes a collaborator in a system of exploitation, unbridled lust, vanity, and greed, in which she and other victims are always the losers.
