The film deals with the sex life of a young New York City woman, Kitty, and her boyfriend, Stud. Stud is brutal and oafish but Kitty is enamored with his sexual performance. They sometimes engage in light sadomasochism, with Stud belt-whipping Kitty. Stud later posts a sign on a bulletin board inviting people to a party. Several people show up at Kitty and Stud's apartment and they engage in group sex, with Stud servicing all the women.
