At the beginning of the Second World War, Czech music student Honsik comes to Germany from Prague to join a "foreign worker company". After rescuing a boy from the rubble of a bombed-out house, he himself is seriously injured and taken to a hospital in Stralsund. There he is regarded as a second-class citizen and the Germans are preferred to him. Nurse Käthe stands up for him, cares for him and defies all prohibitions. A love affair is kindled between the two, but it is not under a good star. Honsik tries to flee to his homeland with his comrades and Käthe supports him. At the last moment, however, Honsik realizes that his love for Käthe is stronger than his homesickness and makes his way back. Once back home, he can only watch as Käthe is arrested by the Gestapo. With the help of a resistance fighter, the young man from Prague manages to escape after all.
