One building. One day. 40 people swapping rooms. “Kinzig 9” is a housing project in East Berlin which emerged from a previously squatted house. There are rooms of many different sizes, some of them dark, some of them bright. To keep it fair the inhabitants swap apartments – in one day. The madness of it all puts their noble aspirations to the test.
