Neukölln, a trendy district in Berlin. Living space is scarce here. Without surety, proof of credit worthiness and salary there is no chance at all now. Thies knows this game; he works for a real estate management company and watches that the rules are upheld - until he meets Bruno and Sonja. He provides the dissimilar siblings with a flat free of charge on the quiet. And enters into an affair with the brother. Step by step he becomes more deeply immersed in the secret of the "siblings". A Berlin film about a loner who gets caught up. About a couple with unclear residency status. About a city everyone wants to live in..
