Sarah Killian is not your average thirty year-old single woman. Foul-mouthed, mean-spirited, and a text-book-case loner. Also, she is a Professional Serial Killer. Sarah works for T.H.E.M. (Trusted Hierarchy of Everyday Murderers), a secret organization of murderers for hire headed up by the mysterious Zeke.
But a wrench is thrown into the clockwork of Sarah's comfortable lifestyle when, on her latest assignment, she is forced to take on an apprentice, Bethany--a bubbly, perky, blonde with a severe case of verbal-vomit. In short, Bethany is everything Sarah is not.
Will Sarah be able to adjust and work with her new apprentice, or will she break her contract with T.H.E.M. and murder the buxom bimbo?
