A woman with an abnormal obsession for stomachs appears, deceiving young girls by pretending to conduct model interviews, then tormenting them for her own pleasure. Suddenly demanding, "Show me your stomach," she tears open their clothes, clamps a hand over their mouths from behind, and restrains them tightly. Using a cloth soaked in chloroform, she renders them unconscious without resistance. The film depicts extreme scenes of her mercilessly abusing the helpless, collapsed girls' abdomens.
