Fresh-faced newcomer Sarina Tohata joins a porn production company as an assistant director. She is serious about her work but fascinated by sex, and the toys around the office and acts performed before her on set awaken desires she can no longer suppress. She becomes so uninhibited that she secretly masturbates at work and starts wondering whether she is better suited to being a performer than an assistant. Encouraged by a senior colleague, Sarina decides to make her porn debut. Though hesitant before the camera at first, she gradually loses herself in pleasure as the line between her job and her sexuality disappears.
