In 10th Century Scotland, Brianna, a voluptuous maiden of the Highlands, makes a daring attempt to convince her lover, a newly ordained monk by the name of Gregory, to run away with her to the south. Under the guise of a monk's tunic, she succeeds in secretly joining him within the dank walls of Boarhaven Monastery. But no sooner are the two lovers reunited that the monastery suddenly comes under attack as a horde of blood-thirsty Vikings unleashes its ruthless fury on sacred Christian soil! In the ensuing chaos, the beautiful Brianna will have to use all her wits and charms if she is to survive the brutal assault by the invading Norsemen, whose leader is none other than the infamous Eirik Bloodaxe!

After Eirik's triumphant return to Ekkofjord, feelings of jealousy quickly boil within Eirik's wife, Gunnhild, as she lays eyes on Brianna for the first time. To appease tensions and to help distract Brianna from the worrysome prophetic visions that plague her mind, Kleeah guides the young woman to a chamber within the Great Viking Hall known as the "Forbidden Room"... wherein pleasures of the flesh abound. Meanwhile, unbeknownst to Brianna, her younger sister Fiona has been taken captive by Sir Marshall, a demented Scottish Knight, and his acolyte, a Century old witch named Kassandra. The pair puts into motion an evil plan that could spell doom for the Gordon sisters.

Brianna and her sister Fiona have been reunited at last and are now living amongst the Vikings. However, Fiona is still haunted by her recent trauma at the hands of her captors, which is manifested in the form of a recurring nightmare in which the Scottish lass is sexually tormented by the dark witch and her pet Hellhounds. Brianna, who has been assigned work in the Viking armoury, begins taking an interest in weaponry and the art of warfare... a first step on her path to becoming a shieldmaiden! Harking back to an earlier time, we get a glimpse into Kleeah's past, during which we learn more about how the sorceress joined Eirik's crew and we also meet a blind, sensuous sword dancer who may hold the key to unlocking the meaning behind Brianna's eerie visions...

Brianna's visions led the young woman and her adopted Viking clan to the distant lands of Iceland, where the border between dreams and reality seems to blur... The objective of this trip? Rescue the pretty Ragnhild, daughter of chief Eirik, whom Brianna sees in a dream - and whom she believes to be prisoner of the red-haired witch and her monstrous creatures. But it may already be too late... Threatened by the witch's black magic, prey to increasingly real nightmares and fantasies, but also fought even in her Viking circle, Brianna will have to redouble her ingenuity and charm to get out alive. And save her clan with her.

As the Winter Solstice quickly approaches, Sir Marshall's plan is set into motion and a horde of undead Norse warriors are poised to invade the sleeping inlet of Ekkofjord. Brianna's only hope of stopping the impending onslaught in time lies within the haunting visions of the future which are increasingly afflicting her mind. In the meantime, Fiona, who's looking to escape a ritualistic sacrifice, takes shelter in a dank cave while she awaits the end of the conflict... only to discover the remote cavern is inhabited by an ominous giant creature!
