Channel 4’s latest Scandi noir import comes from Norway, in the form of this eight part thriller. Set on the border between Norway and Russia, we follow police detective Thomas Lonnhoiden (Espen Reboli Bjerke), a man new to the area. A girl finds a severed hand while playing near a river. In less than 24 hours she disappears and Lonnhoiden is tasked with finding her. The River is on Channel 4 at 22.35, with the rest of the series available on All4 afterwards.
