Mistress of Bones (10:43)
Crypt TV Wiki; IMDb; YouTube

There are a couple of grave robbers, one of whom is apparently collecting items of power so he can, like, channel a god of death or something. And I guess he summons a monster. But then a woman in a mask shows up, and I guess she's the title character (played by Nicole Muñoz), who fights the monster and then one of the grave robbers and then... I dunno, I didn't really understand everything that was going on, but it seemed cool, and I'd like to see the story continue.
