The film is a Kafkaesque tale of an insignificant Water Inspector who arrives at a giant remote building in order to register the residents’ water meters. Before he knows of it, he finds himself trapped inside the building facing an “Alice in NO-Wonderland”-like maze of obstacles. In his attempt to escape, perception of reality, the rational, and the remnants of his human existence is turned upside down.
When a homeless Romani boy is arrested at the Danish border for possession of a missing public servant's passport, police inspector Carl Mørck and Department Q are tasked with finding the connection.
