Trick The Treat

When her enigmatic billionaire boss Emmanuel invites the beautiful but bumbling sales associate Charlotte to a Halloween party, she gets quite the surprise. After his three equally handsome and rich partners arrive and she realizes she's the only guest for this party, the men reveal they are vampires dead set on transforming her to make her one of their pack.

Charlotte has qualms until they explain what they'll do to turn her.

And then the fun really starts.
