Two "dumb-bells", Hugo and Tincek, steal a camera from a lunatic asylum and escape. They want to make a film about a hero, who saves a girl and gives her a kiss at the end. Hugo shoots the film and Tincek plays the main character. They are making the film by shooting "ordinary" people, without them knowing what is really going on. This leads them to prostitute Magdalena, who wants to commit suicide.
