Your Presence Is Imperative(1984)

Original title: Erscheinen Pflicht

Elizabeth is an open-minded young person - curious and unbiased. She is sixteen, goes to secondary school and things are really going well, not least because her father, a Party member, occupies a privileged position. But then the father suddenly dies. Elizabeth feels lonely and abandoned, all the more so because her brother has long since severed all ties with his father.
