Outer Senja in 1877. A young girl is found apparently lifeless among flotsam and seaweed. The storm has washed her ashore. Miraculously, they revive her, but she has lost her memory, and no one knows who she is or where she comes from. They call her "Båremor" or "The Girl from the Sea." A fisherman and his wife take care of her, and it gradually becomes clear that she has extraordinary abilities. Among other things, she plays the organ beautifully. The girl feels like a stranger among the weather-beaten coastal people, and she is driven to track down her original home. During her escape, she hides in the boat of the wandering vagabond Borr, a notorious and wanted daredevil. On the run from the sheriff and the priest, they try to find their way back to her birthplace.
