Yes, the plot is pretty weird. There is this "star" (whose incarnation is a woman dressed in white) and some random guy who falls in love with her. There's the arc of "if you cross a specific border you'll die" which applies to our lady "star". Well, I also remember that they have some kind of a tubular case, and when one opens it, lightning files out.
I watched the film somewhere around 2010, it's in English and when I try to remember it, I get the vibe of a mediocre Hollywood fantasy romance.
