The Unsuspecting Angel (1936)

Original title: Der ahnungslose Engel

Jozi's aunt runs an inn near the border and has a little side-job: she smuggles. Poor, naive Jozi doesn't know anything about it. Jozi falls in love with the young border patrol officer Hans and her feelings are amply returned. But Hans' supervisor suspects Jozi of smuggling and tries again and again to lead her into illegal temptation. Finally, Hans sees Jozi in a dance bar together with smugglers and believes, too, that she's one of their accomplices.
