The film's main storyline follows the life of Otík, a mentally retarded young man, in a tight-knit village community. The sweet-tempered Otík works as an assistant truck driver with Mr. Pávek, his older colleague and practical-minded neighbor. Pávek's family takes care of Otík, whose parents are dead. However, the two coworkers become at odds over Otík's inability to perform even the simplest tasks. Pávek demands that Otík be transferred to assist another driver, who happens to be a choleric and suspicious man named Turek (''Turk'' in Czech). Rather than work with Turek, Otík decides to accept an offer of employment in Prague, but finds he does not fit into the city life. After discovering that the transfer of Otík to Prague was a trick by a crooked politician to get a deal on Otík's large inherited house, Pávek agrees to give Otík a second chance and retrieves him from the city to resume their work together.
