When teenaged misfit Kory Mowat violates Norway's Resistance's codes of audacity and silence, he and his brothers by honor learn hard truths about their friendship. The occupation of Norway by the Germans upends Kory's mapped-out life. Joining the Norwegian Resistance and using codes from a game called Solsvik Bridge, he and his friends smuggle munitions and pass information that they place inside German propaganda. But when he and his Nazi-collaborator brother vie for the attentions of an unscrupulous girl, Kory's naivete and combative rivalry blind him to what he promised to uphold. Just when he thinks he has made it and that he and his friends can conquer the world, and for all his betterment, his touchstone is ripped away, leaving Kory to learn the truths of friendship.
