There is an age when children stand upon a threshold. Confronted with the adult world in a different way, they suddenly begin to enter into it. Whereas this often has a certain appeal, sometimes it is also a gamble. Marie, Arthur, Emine, and Christian find themselves exactly on this threshold in their lives. The film accompanies them in this balancing act for an entire year. Marie lives in a single-family house in a residential area on the outskirts of Berlin. When she is alone in the afternoons, she plays teacher or explores nearby empty houses that are destined to be torn down. Arthur's favorite pastime is Minecraft. Or he talks to friends about Minecraft. For the rest of the time he offers to explain the meaning of senility to his two younger siblings. Emine and her girlfriends move through the streets of Neukölln singing, dancing, or recording videos. If it is not the city that belongs to them, their neighborhood definitely does. Christian has three older brothers. All of them cool, good-looking, funny. While they are his role models and best friends, he is often busy simply trying to keep up with them. Four kids in Berlin who do not know each other but who share the same age and part of their destiny.

Nina Wesemann was born and raised in Cologne. In 2010, she began her studies at Munich's Hochschule für Fernsehen und Film (HFF) in the section Documentary Film, where she worked on numerous smaller and longer films as director and camerawoman.
