Maria, a poor orphan, lives with her grandfather Grassl in a remote fishing hut on the shore of Bodensee, where she ekes out an existence with her fishing-lines. Her mother is long dead, and the identity of her father is unknown. The nearest neighbours are the Bruckbergers, who are wealthy ... in fact, the Bruckberger daughters have a motorboat, which scares away the fish Maria needs to catch for her livelihood. But Karl Bruckberger also has a handsome young son, Hans. (imdb User Comments)
