The tide washes up a slain Viking warrior on the beach in Husum: the unusual "dead body by the sea" is not a case for historians, however, but for the police and detective Ria Larsen. Marlene Tanczik plays the battered but combative investigator in the second film in the Saturday evening crime series on the first channel. Christoph Letkowski plays her partner Brandt, who believes in Ria's special abilities and is loyal to her.
