Orimoto and his wife move to an apartment in the city center due to her husband's job transfer. Serino, who used to live in the countryside, was excited about life in the city. One day, Serino goes to the room next door to say hello about moving in, but the room next door is a room full of trash college students who repeatedly engage in rape-like acts. Serino senses a disturbing atmosphere, but the college students who notice her beauty half-forcibly lure her into the room and use her as a sex toy without asking.
