After his father's death, a young man (Gregor Bakovic) uses the black mourning flag and sews himself a pair of trousers. He then takes a train trip and meets a variety of bizarre characters, including a stowaway, a deaf-mute duo, a balloon-seller, a bird enthusiast, and an attractive girl (Barbara Cerar). Their railway romance gets derailed, but a variety of sight gags and caboose comics keep the film on track and in loco motion.
