Martin's apartment building is undergoing renovations, and there is a large hole in his outside wall. A thin sheet of plastic cannot block birds from entering the apartment. Bricks are set up to fill in the hole, but the landlady fired the contractors. Martin and Nina try to have a romantic dinner in Martin's apartment, but an emergency protest comes up, and Nina needs to join it. Nina uses the bricks from the apartment to fill up a factory's drainage pipe, and is arrested. (thetvdb.com)
