In the 2008 Czech film Bathory (just now released 2012 as Bathory: Countess of Blood) totally hot babe Michaela Drotárová plays Erika, a maid to Anna Friel's also pretty damn hot Erzsébet Báthory. While this particular maid being so incredibly smoking hot may not bother the Countess all too much, her being raped out of drunken lust by the King's brother (or was that the King himself?) and subsequent peeping in on her post-mortum activities causes a bother.
Of course it doesn't help that this bitch is tossing herself at Bathory's object of desire, her gift the painter. Not only is she constanty rubbing her titties all over the guy, but she steals the ring that the Countess gave him and mistakenly flaunts it in front of her.
Then she goes meddling in places where she shouldn't be. Looking upon things she shouldn't see.
