Watch Ball at the Metropol (1937) Official Trailer

At a ball at the Metropol, the married Margit gives a harmless kiss to a one-time friend from her childhood and cousin, Eberhard. The two notice, however, that Margit's ill and jealous husband observed them from a distance, because he recognized the coat she recently purchased. Quickly, Margit asks the salesgirl Trude to put on her coat and meet Eberhard in the lobby. Things take a decidedly different turn, however, when Trude and Eberhard fall madly in love with each other.
