Norwegian Ninja is the true story of how Commander Arne Treholt and his Ninja Force saved Norway during the Cold War. In 1983 the Ninja Force discovers that the sinister NATO force Stay Behind, who take charge in times of war and emergency, are planning a coup-d'état in peacetime. Treholt and the Ninjas see only one solution: a full can of whoop-ass.
Detectives Jonas and Erik are called to the midnight sun country of northern Norway to investigate a recent homicide, but their plan to arrest the killer goes awry, and Jonas mistakenly shoots Erik. The suspect escapes, and a frightened Jonas pins Erik's death on the fugitive. Jonas continues to pursue the killer as he seeks to protect himself; however, his mounting guilt and the omnipresent sun plague him with an insomnia that affects his sanity.
