Three unmarried sisters, Katka, Eliska and Magda, go for an extended wellness weekend to a luxury hotel in Spindleruv Mlyn. Katka, the oldest, hates her job, where she spends so much time that she has no chance to make friends. Magda is a tattooed free-thinker and the youngest, Eliska, who thought up the whole trip, is quite a successful model. The ladies plan to ski and pick up some rich men. However, there was a mistake in the booking system and all three end up in alternative accommodation, which is far from luxurious.
