Acquitted follows the story of Aksel Borgen, a Norwegian business man who has worked his way to the top during his 20 years in Asia having left his native town after being acquitted of the murder of his high school sweetheart. When his home town's cornerstone business is threatened by bankruptcy, Aksel returns to save the place that once turned its back on him. The past has not been forgotten. His arrival tears old wounds apart and new conflicts arise as the past meets the present. Acquitted shadows a battle of guilt, revenge and hope of reconciliation, the man who pleaded not guilty is still judged by society.

In the near future a new phenomenon starts happening all over the world with powerful flashes of light occurring in the ocean and people from the past mysteriously reappearing. Called “beforeigners,” these people come from three separate time periods: the Stone Age, the Viking era and late 19th century. A couple of years later, Alfhildr – who comes from the Viking Age – has to partner up with a burned-out police officer, Lars Haaland, to investigate the murder of a beforeigner. The pair begins to unravel a larger conspiracy behind the origin of the mysterious mass arrivals.
