Alice and Horst paints a moving portrait of two siblings from Saarbrücken whose lives were shaped by their family’s antifascist resistance. As children, Alice Hornung and Horst Bernard were forced to flee from the Nazis into exile in France, where, despite constant danger, they also experienced great solidarity. After their return they continued their parents’ political commitment: against fascism, for peace and disarmament. The film combines personal memories with rare archival footage and portrays two individuals who, well into old age, remain unwavering in their commitment to justice and remembrance.
