Finally, our Heidi has arrived at Munich, to take her position as a housemaid at the family Sennemann. But within her heart she still is with her beloved Bavarian mountains, her grandpa and the "goat-Willy". But in the cosmopolitan city with a lot of sex she soon realizes that the "upper class" gets laid everywhere, even "a little bit pervy". Daughter Vera shows her then the nightlife of Munich. This almost leads all to a catastrophe, but her grandpa and the "goat-Willy" are about to start a rescuing mission.
