Warsaw at night. Two young people, Eve and Chicor, are walking through the city after a wild party. Both have had something to drink. The girl coquets her partner, provokes with the promise of a "reward" for a nice evening. Chicor accepts the challenge and walks Eve home. The girl invites the boy to her apartment. A few minutes pass drinking wine and increasingly frivolous flirting. Everything seems to be moving towards a rapprochement. But this night will not end with easy, non-committal sex. Both parties are hiding under different masks. Eve is amused, seems confident and consistent in her ambiguous game with her boyfriend. Sometimes she resists her admirer, at other times she provokes and tempts him again. Chicory is intrigued by the girl's behavior, but slowly realizes that Eve is not just another prey, a woman for one night.
