Hello dienstmann (1952)

Vienna, 1951. Ferdinand Godai is a professor of operetta at the Academy. Disguised as a porter for a costume party, he ends up in a drunken mood at the South Station. There he meets Anton Lischka, a genuine Viennese porter with a fiery temper, who asks him for his collegial help. Ferdinand falls in love with the sweet Gabi, who turns out to be a new colleague at the Academy. A series of adverse circumstances force him to continue his complicated double life as a fake porter and a genuine professor. Lischka, who becomes increasingly annoyed by his "colleague's" clumsiness, is also drawn into the confusion. Only Gabi sees through the deception and even contributes to its escalation in order to teach her beloved professor-porter a lesson in womanizing.
