Registration of the fourth theatre program by the Dutch comedy duo (Erik) van Muiswinkel and (Diederik) van Vleuten. The comedy duo broke up after their last program: Van Vleuten has started a second-hand bookstore and seeks solitude. The TV-personality Van Muiswinkel regularly visits his intellectual friend and gradually takes on increasingly insane guises.
