It's 1914 and Professor Hermann Eth and his wife are living a happy, bohemian life in Aberystwyth. But as the First World War unfolds tragically in Europe, fear and panic take hold at home. Whipped up into a frenzy of hatred and prejudice, a violent mob decides that this German academic and his free-spirited wife are no longer welcome in the town. Driven from his work, his friends and his home of forty years, Hermann grows increasingly dependent on his wife. Together they must fight to ensure that they can survive.
