As a conservationist, he is to grant permission for an adaptation of a Baroque château to office spaces. On the road, a pretty young hitchhiker named Eva (Ida Rapaicová) stops him. Eva is Slovak and her spontaneous behavior enchants Jirí. He thus does not mind making a short detour and takes Eva all the way to the luxurious cottage of her parents.
