Dr. Matilda Schmidt is used to handling the paranormal world's most twisted cases. So when the Baba Yaga asks her to fill in for Roger the rabbit Shifter while he's in wank-flick rehab, she's more than happy to oblige. With her super mega genius seven-year-old daughter in tow, Matilda packs her bags and heads to Assjacket, where she learns that there's a rogue Hexer hanging around town, and a series of attacks has the locals worried.

When Matilda's inaugural session with Zorro the fainting goat Shifter is interrupted by a leather wearing, white-haired, amber-eyed—and really hot—stranger, she's shocked to learn that he's been transported from another realm to hunt the Hexer. Together, they'll have to uncover the real reason the Hexer has targeted Assjacket, even if it means confronting the troubling truth about Matilda's own daughter.
