In civil war-ravaged Norway, the King, aided by rebel group the Birch Legs, fights for survival against the Church's Bishopsmen, who seek to supplant the throne. On his deathbed after falling ill, the King soon welcomes a son, born in secrecy, as half the Kingdom wants him dead. Tasked with guarding the only remaining heir to the throne, two Birch Legs warriors, Skjervald (Oftebro) and Torstein (Hivju), escape with the infant and must traverse treacherous landscapes to protect their future King.
