At night, the hospital becomes a breeding ground for perverted nurses and their lewd desires. Targeting male inpatients, they go far beyond basic care, tending to their lower bodies with lustful intent. Bold new nurses seduce their senior colleagues into lesbian affairs, while veteran nurses become obsessed with illicit sex with doctors. Some even descend into madness, engaging in orgies with patients right inside the hospital rooms. The night shift reeks with the nurses' rampant sexuality.
