Beforeigners

In the near future, a new phenomenon shocks the world as powerful flashes of light in the ocean coincide with the inexplicable appearances of people from the past. Hailing from three different time periods -- the Stone Age, the Viking Era and the late 19th century -- these time travelers referred to as "beforeigners" have no memory of what has happened or why. While no one understands how this is possible, the refugees keep coming with no way back, and it is up to Oslo police detective Lars Haaland to investigate. Later, he works together with Oslo's first multi-temporal police investigator, Alfhildr Enginnsdottir, to solve mysterious murders and uncover the truth about the time-traveling refugees.
