HBO has released a trailer for Beforeigners, a six-part sci-fi drama that debuted in Norway last year and is just now beginning a U.S. run. The high-concept tale, the first Norwegian-language series produced by HBO Europe, explores a world in which people from the Stone Age, the Viking Age, and the 19th century are mysteriously transported into modern-day Norway. There, some integrate into society—like, for example, an 11th century shield-maiden-turned-investigator played by Krista Kosonen—while others remain enemies of the people. There’s also, apparently, a killer on the loose. Okay, then.
