Alexander, a 20-year-old conscript who has just completed his army service, returns to his native town on the bank of the river Danube. Here, his friends are killing time in the cafe, dreaming about the coming summer. Their lives are before them and they all plan to seek happiness. Alexander's dream is to go to university and be with Asya, a girl he met briefly but memorably during his army service. While waiting for the results of the entrance exams, Alexander works as warden and tour guide at the medieval fortress near his town. One day a noisy company stops in front of the heavy, studded iron gates of the fortress. Even though the fortress is closed for restoration and a group of school kids has just been turned away, the boss orders Alexander to let the noisy company in as an exception. Alexander refuses to obey and loses his job. Asya is among the young people in the privileged company.
