Helle (Anna Demetriou) is the only child of King Asmund and Queen Alva and the one true heir to the Viking kingdom of Volsung. Yet she is unaware of her true lineage, for Helle was switched at birth with her cousin, her evil uncle Bard having convinced King Asmund that a female heir would weaken the kingdom. On the run after being framed for the murder of her father, the king, Helle seeks guidance from the god Odin (Terence Stamp) to gain the training and wisdom she needs to take back Volsung and fulfil her destiny.
