In 1974, Karo sets out from Belgium with her dad, Raven, and her mom, Dalia, to start a new life in Amsterdam. They join a group that is taking over a vacant building and setting up a new society based around the vast common room they all share. No walls, no rules, only love. Raven builds fantastical see-saw constructions on which Karo and her friends can play. Karo even gets a swing in the common room, which gives her a view of the adults below: eating, bathing and debating together. But when Raven begins a flirtation with a new Dutch woman, he puts his ideals in defence of his desire. And, the family that left Belgium begins to fray as the forces of free love and jealousy threaten to pull it apart.
