Petr and Hana, who after years together share their unspoken erotic fantasies. What begins as an innocent conversation gradually turns into experimentation with a non-monogamous approach to their relationship.

Hana (Hana Vagnerova) is starting to feel that her relationship with Petr (Matyas Reznicek) is getting into a rut. So she decides to liven things up and starts sharing her erotic fantasies and secret desires with him. It's just a small step from words to action. Soon they are exploring their own intimacy, trying experiences with other partners and increasingly pushing the limits of just how far they can go in love and sex. However, such an experiment with freedom can easily get out of hand.
