A Bavarian comedy centered around Gusti, the lovely waitress of the restaurant „Bratwurstglockl“, who is adored by all the men. When the spoiled snob Carl Maria complains to the manager about the restaurant, Gusti is summarily dismissed and accepts the invitation of the poor chamber singer Gottlieb Bumm to accompany him on a three-day trip to the Zugspitze he won in a contests. While there, they both live well above their means and Gusti runs into Carl Maria again.
