This looks like it could be cheesy fun. No release date announced state side just yet.
The plot synopsis:
St. Niklas, a bishop fallen out of grace, who travels in the middle ages with his gang of robbers and thieves through the countryside, raping, plundering and killing. When villagers take the law into their own hands and murder the bloodthirsty bishop and his thugs by setting the ship on which they travel ablaze, Niklas vows revenge.
Now every time there is a full moon on December 5, the date he died, something that on average takes place every 36 years, St. Niklas and his helpers will rise from the dead and take revenge in a horrible way.
