Apparently, he and the Viking go Way Back. They decide to keep the girls away from the Evil Sorcerer and almost immediately proceed to fail. The Viking rescues Mira, the younger, and Erlich and Mara get captured and dragged off. Pointless stuff happens. Unfortunately, it comes up only once, two scenes after it is first mentioned, and is used only so a sex scene can be played out without compromising the R rating.
Pointless stuff happens.
Mira and the Viking raid the fortress, trying to rescue the others. They end up underground. The Viking fights endless hordes of zombies while Mara and Erlich are prepared for the sacrifice. Then it finally occurs to Mira to shout the Sacred Words of Power given to her by the Good Wizard. I'll even avoid mentioning the fact that if she can just shout this one word of power and beat all the bad guys, it renders the proceeding forty minutes of film meaningless.
