Wrong Floor(1916)

Mr Vang, a clerk, has just moved into the fourth floor of a block of flats – and he has already gained a reputation as something of a troublemaker. The woman, a professor’s wife, who lives just below his flat has so far only been indirectly acquainted with him in the form of stomping feet and noise lasting into the small hours. She hopes to meet him face to face soon so that she can give him a thorough talking-to – and her wish is about to come true in a quite unexpected way. When the clerk returns home after a boozy night on the town, he mistakenly locks himself into her home, triggering an array of comical situations. (Stumfilm.dk)
