A schoolgirl in uniform responds to a man's call, sitting on a chair and exposing her innocent body. Fearing her family's financial collapse after news that next month's school trip has been canceled, she worries about her parents and older sister. Believing everything is her fault, the girl is summoned to a room on suspicion of shoplifting. After a brief conversation, she becomes mentally and physically exhausted. Facing threats of a home search, arrest, and a possible 10-year prison sentence, the girl clings to the man as her only hope. In the end, she resolves to atone for her sins by offering her own body.
