On a barren and stormy island, fishing families eke out a meager existence on what they can catch during summer, and what washes ashore during winter. But little has been washing ashore of late, and their situation worsens. Elders recall how twenty years ago, when the lighthouse keeper’s beacon went dark, a cargo ship broke apart on the cliffs. It proved a bountiful accident for the fishermen. Today people on the island view the conscientious lighthouse keepers with evil hungry eyes...

Young, pretty Milli is passionate about winter sports, and of all things, she wins a vacation trip to the Baltic Sea at her company - in summer, of course. After her first dip in the sea and meeting a nice young man, her initial displeasure fades. But not for long, because Robby turns out to be a filou, shuns regular work and is also a womanizer. After some confusion, Milli's vacation ends well after all. She goes home with Robby, who wants to take a job as a car mechanic in her home town of Suhl.
