Anna, a student of psychology, returns home early after a really bad day and finds that her roommate Lina works as Mistress sometimes. Lina convinces Anna to try her first BDSM session. After the session, Anna chooses BDSM as the topic for her dissertation. So Anna decides to become a Dominatrix. Nevertheless, it’s not enough to explore the world of BDSM. She will agree to offers and practices (within the limits of criminal code), go to the parties, try to expose latent doms and subs, try this subject with her boyfriend, friend, scientific adviser, and eventually her neighbor. Anna will try to treat patients in the clinic through the lens of domination and submission, she’ll do research in the university, etc.
