A beautiful young woman suffering from severe constipation collapses in public and is rescued by a kind stranger, then taken to the hospital. Ashamed and vulnerable, she undergoes a humiliating examination where the doctor inserts fingers into her anus to manually remove impacted feces, followed by an enema. Later, two beautiful female patients, Junko and Rina, are placed in the same hospital room. Junko, injured and unable to open the bathroom door, struggles to hold back her urge to defecate, while Rina remains indifferent. Time passes, and by the time the doctor arrives, it's too late—Junko defecates uncontrollably under the gaze of others. Meanwhile, a negligent nurse trainee insults the female doctor and faces continued punishment involving enemas and anal degradation, escalating the situation further.
