In this updated and broadly revised adaptation of Dostoyevsky's novel The Idiot, Navrat Idiota follows Frantisek (Pavel Liska), a young man whose intelligence does not appear to be overwhelming. As Frantisek waits in a train station, he spots Anna (Anna Geislerova), a beautiful young woman who is running for the same train he will be taking. Anna ends up dumping a carton of yogurt on him, and she later discovers that they've been assigned the same sleeping car. Arriving in town, Frantisek observes a young couple (Olga (Tatiana Vihelmova) and Emil (Jiri Langmajer)) breaking up, and later that night he attends a dance, where he sees Anna yet again. After the dance, Anna discovers that Frantisek has nowhere to go and offers to let him stay at her flat for the night. In time, Anna begins to confide in Frantisek, as do Olga and Emil, though he has a secret that could in time cause serious problems for them all. Navrat Idiota was written and directed by Sasa Gedeon, who made a made a big splash with his first film, Indinaske Leto.
