It's hard for me to resist a B-movie about Vikings, especially one that's only an hour and a half long. In Northmen, a sturdy band of Vikings, kicked out of their own country for not supporting the king, is shipwrecked on the coast of Scotland, where after climbing a cliff, they're confronted by a bunch of armed men. (It's best not to ask how these men knew they were there. Maybe they overheard them talking.) The Vikings are heavily outnumbered, but they kill everyone except the one man who's required to escape and inform the king of the sad events.
Why inform the king? Because locked in a wagon is the king's daughter, who's being transported to her wedding. (Transported from where? Who knows?) The king is naturally disappointed, and his evil mercenaries, one of whom kills the messenger, go after the Vikings, who are holding the king's daughter for ransom.
The Vikings meet a Christian monk who lives in a stone tower. He's also mighty good with a rod and a staff. When the mercenaries catch up and burn the tower everyone escapes into underground caverns.
After that it's mostly a "who's going to live and who's going to die?" movie, with lots of action and the one essential element to make the movie worthwhile -- a scene on a board bridge suspended across a gorge by ropes. There's even (almost) quicksand! If you're going to carp about "realism" and stuff, don't even bother with this one.
There's plenty of scenery, and the acting, by people I've never heard of, is adequate. The mercenaries ("I think they're from Carpathia") are truly evil. They howl and growl a lot. But then so do the Vikings.
This isn't a movie I'd recommend to everyone, or even to anyone, but I had fun watching it.
