A married nurse named Sayuri works at a mid-sized hospital in a certain city in the Kanto region. She is a newlywed, having just married Dr. Yajima, a surgeon at the same hospital. Today, she is also a white-clad married nurse caring for hospitalized patients with a gentle smile. The male patients, fixated on the swelling of Sayuri's female body, accumulate pent-up sexual desires and continue to cast greasy gazes upon her. Then, one night, they carry out a wicked scheme against the nurse's female body during her night shift.
