Jak se naučit švédsky(1979)

The protagonist is supposed to go to a graduation reunion and, because she is ashamed to reveal that she is still lonely and unmarried, she makes up a story that her husband was a Swede who came to the Czech Republic for assembly and that he died suddenly. She tries to fend off the prying classmates with a photograph of her "husband" with his colleagues from a newspaper article, where she accidentally shows a man. What a surprise the classmates experience, and what consternation she herself experiences, when the freshly deceased man in question suddenly appears at the spa where the incriminated alumni reunion is being held! And not only is he alive, he even speaks Czech suspiciously well...
