For it's budget this film is actually pretty good. It's loosely based off of the idea of A Fistful of Dollars and it works well for this type of genre of film. Kain is basically getting as much cash as he can while he pits two opposing clans against each other that fight for the only water source around.
Naja is the "Sorceress" but she doesn't do much except run around naked, even after she's freed. Yes, after her freedom she still bares her boobs like it's normal. Maybe it is for her but she doesn't appear to be the town slut so I don't get it.
Now, this movie would have been great with a bigger budget but it has one thing I've never seen before.... a.... hot... woman... with... four... boobs!
