广告代理店的广告撰稿人新谷公平，在妻子半夜将陌生男性带进自己家的现场，与男性发生争执后，从公寓的楼梯上摔了下来。被送往新谷的大学医院的新人实习医生吉川绿，因为不擅长急救患者，连点滴的针都不让打。结果，新谷被诊断为股骨骨折、痊愈1个月，在该医院使用费便宜的大房间里度过住院生活。但是，新谷旁边床上的患者是一起坠落的男性如月十津夫……

When a hard-driving copywriter (Hiroyuki Sanada) discovers his comely wife (Keiko Saito) is involved in a scintillating game of strip rock-paper-scissors with some guy clad only in a pair of boxer shorts and Mickey Mouse ears, he is less than happy. When the stranger tries to make a run for it, a fight ensues between the two men, and they accidentally tumble down several flights of a concrete stairwell. One hurried ambulance ride later, the copywriter finds himself in a private teaching hospital equipped with the latest gleaming gizmos. Meanwhile, a young internist (Hiroko Yakushimaru) girds herself for her first emergency room case -- the battered copywriter. After giving a curt bow and a nervous "Good Evening," she accidentally jams a syringe into his bloody wound. Soon the absurdity of their situation, along with their medical misery, binds the two men and their blundering nurse together.
