With business at a standstill because of Prohibition, Dutch-born brewer Hans Wagner (George Sidney) returns to his homeland, hoping to jump-start his business. Invited to join a fraternal lodge, Hans dons the conclave's uniform, whereupon he is immediately mistaken for the Prince of Pilsen (Allan Forrest). Before he quite knows what is happening, Hans has been whisked off to the royal palace, where he is expected to marry Princess Bertha of Thorwald (Myrtle Stedman). Assuming that it's all part of his lodge initiation, Hans jovially agrees to go through with the wedding ceremony. The truth is revealed at the last minute, by which time the real Prince has fallen in love with Hans' daughter Nellie (Anita Stewart). The Prince of Pilsen was adapted from the popular musical comedy of the same name. ~ Hal Erickson, Rovi
