The Passing of the Third Floor Back(1918)

To a rooming house which has fallen on hard times comes The Stranger, an unknown but gentle man who is given the back room on the third floor. His arrival marks a change in the lives of all the boarders, from the girl resisting her parents' pleas that she marry the lecherous Mr. Wright, to an architect and a pianist, both of whose dreams are near destruction from their own discouragement.
