Willi Forst ably essays the title role in the frothy musical Der Prinz von Arkadien. Preferring to write songs and dally with the local damsels rather than concentrate on matters of state, young prince Forst is ordered to leave Arcadien and go into brief exile. This suits him fine, as he never cared for the responsibilities of his office anyway. Upon taking up residence in a tiny European village, Forst falls in love with actress Lianne Haid, who does not recognize him. Unbeknownst to Forst, Haid was also exiled from Arcadien for singing a song unfavorable to the "playboy prince." Returning to her homeland, she intends to humiliate the prince in public but changes her mind when she discovers Forst's true identity. And that's only half the plotline!
