Fangs With Benefits follows Molly Mason, an overworked employee who is passed over for a promotion in favour of a handsome but hopelessly inexperienced new hire, Elijah Thorne. Frustrated that she's been assigned to train him, Molly is even more surprised when she discovers Elijah is secretly a vampire trying to adapt to modern human life. They strike a mutually beneficial deal: Molly will help Elijah blend into the human world, while he helps her achieve the promotion she deserves. But as their fake no-strings arrangement turns into real attraction, keeping business and pleasure separate becomes far more difficult than either of them expected.
