End Of August In Ozon Hotel

It is 25 or so years after a nuclear war, and a few hardy young women, and an older leader, are wandering (in Czechoslovakia?) in search of canned food from before the war that can be safely eaten. No men apparently survive, being less resistant to radiation. They come across a mountain resort hotel, the Hotel Ozone, where an old man lives alone with a wind-up record player and old books and magazines. The young women, raised as barbarians, act the part.
