One year in the sad life of Katsuni, directed by the star herself. A year of boredom, repetitive routines, and the quest for pleasure. Assuming the role of a lingerie saleswoman, Katsuni discusses her experiences the client who invites her to a night of torrid sex, and two couples whom she watches swap partners during the course of the evening. The film also includes her most perverse orgy fantasies. There is even a director of porno movies who invites her to attend a filming. But nothing seems to satisfy Katsuni, not even a night spent with a lesbian girlfriend from her past. Katsuni wishes to relive the night she spent with a stranger, the only night she learned the true meaning of the word orgasm.
