The eight-part series focuses on Anna (Paula Kalenberg) and Paul (Fridolin Sandmeyer), who have been together forever, as well as their friends Julie (Salka Weber), Valentin (Martin Bruchmann), Bella (Mona Pirzad) and Leo (Pascal Houdus). Their lives are running smoothly until Samu (Eric Cordes) returns home with his girlfriend Siena (Lilja van der Zwaag) and proposes a daring game to his old clique that breaks all boundaries: everyone throws their key into a bowl.

Whoever moves in spends the night with the owner of the key. No feelings, no obligations. Just the game. What begins as an exciting experiment quickly turns into an emotional powder keg. Old longings break out, new truths come to light: nothing remains as it was.
