At the funeral of his schoolmate, the nearly-fifty-year old architect Jirí Mánek (Václav Voska) meets his former close acquaintance - physician Jarmila (Blanka Bohdanová). They both are still single. Jarmila has recently returned to Prague after years of work on the frontier. Jirí leaves for a business trip. 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. A romance develops between the two people, so different in age and temperament.
