Men who arrived believing it to be an ordinary hospital were admitted for accident aftereffects or erectile dysfunction. However, this was actually an abnormal psychiatric facility run by Doctor Mero, a sadistic psychiatrist who brainwashed patients and turned them into masochists. The men were forcibly committed and subjected to Doctor Mero's insane examinations and treatments, gradually becoming submissive. As these acts began to bring them pleasure, they progressively transformed into full-blown masochists. Just as Doctor Mero intended, the men refused to leave the hospital of their own will, continued paying exorbitant fees, and became test subjects for increasingly brutal treatments. Used as mere flesh dolls to satisfy Doctor Mero's desires and enrich her, their bodies were ruthlessly exploited until their entire fortunes were drained. Eventually deemed worthless, they faced disposal like garbage, discarded without a second thought.
