Aiming to be a writer, Wilhelm leaves his mother and girlfriend in his home town of Glückstadt in the flat far north of Germany and sets out for Bonn. Changing trains at Hamburg, he notices a beautiful actress, Therese, and obtains her phone number. In his compartment are an older man, Laertes, who mostly communicates by blowing a mouth organ, and a young female acrobat called Mignon, who is mute. The pair have no money, so Wilhelm pays their fare and puts them up in his cheap hotel, where Therese joins them. Bernhard, an awkward Austrian who wants to be a poet, befriends the four. He says he has a rich uncle with a castle on a peak overlooking the Rhine, but when the five turn up it is the wrong place. Despite their error the owner welcomes them, because their arrival prevented him shooting himself; he says they can stay as long as they like.
