Within the close to future a brand new phenomenon begins taking place everywhere in the world with highly effective flashes of sunshine occurring within the ocean and folks from the previous mysteriously reappearing. Referred to as “beforeigners,” these folks come from three separate time durations: the Stone Age, the Viking period and late 19th century. A few years later, Alfhildr – who comes from the Viking Age – has to companion up with a burned-out police officer, Lars Haaland, to analyze the homicide of a beforeigner. The pair begins to unravel a bigger conspiracy behind the origin of the mysterious mass arrivals.
