Die Slupetzkis - Urlaub in Balkonien (2008)

Everyone can see that the Slupetzkis live in luxury. What their neighbors, the Taubers, don't see is that they are broke. So the Slupetzkis only pretend to go on their ostentatiously announced prestigious vacation and instead hide in their villa. But there's something they don't know: their daughter Diana is using the seemingly empty house to spend the holidays with her new boyfriend, Tomek, an Eastern European car mechanic, doing whatever she wants. Unfortunately for Diana's parents, there's nothing they can do about their daughter's plans, because otherwise their cover would be blown.
