The office lady in room 301 just loves sex. She invites the man who has come to deliver the parcel into her room today... In room 302, the couple who are semi-living together start arguing as usual... In room 303, a man is waiting for a call girl with a tense look on his face... Three sex stories take place in three rooms at the same time. This is Yoshihiko Arima's directorial debut, in which he plays four roles!
