Eva, who earns her money as a call girl, learns that she has inherited the Palace Hotel in St. Wolfgang. She immediately quits her job and travels to Lake Wolfgang with her friend Maxie. But immediately upon arrival, they encounter a nasty surprise: the building is an old, dilapidated building with a mountain of debt. What now? The two pretty girls receive unexpected help from six students camping on the hotel lawn. Together, with rags and brooms, they transform the old Palace Hotel into the "Black Horse Inn." But in town, the competition, which, as we all know, never sleeps, is the renowned "White Horse Inn"...
