The night she spends with this alleged terrorist is enough to bring her quiet life into ruins and subject her to police surveillance. Exploited by cheap newspaper sensationalism, Katharina slowly becomes a wider target, with anonymous phonecalls and letters, sexual advances and threats all testing the limits of her dignity and sanity.
