So I saw this movie on TV when I was younger, maybe 8 years ago or more. I remember that the movie was about this evil queen/demon that could only be killed by ice magic. This ice magic was only in a cave that men couldn’t enter though. So a naked woman had to enter and absorb the ice magic.
I also remember a scene where the queen took on a demonic form and the man in the movie took the ice magic and killed her with it.
