After the death of Ellie's uncle Alfie, an infamous magician and occult detective, the 72 devils of the Ars Goetia are mysteriously freed from their infernal realm. It's now up to her to track down each of these demons and damn them right back to Hell... using holy water, conjuration, or just her trusty, rusty claw hammer.
Meanwhile Dora, a detective traumatized by the same events as Ellie, is suspicious of the untimely death of Alfie. As new terrors unfold, the two witness strange changes to the political landscape of Britain: a gibbering madness infecting the population.
Ellie, Dora, and Carlin are shocked to find what Theo, a wealthy member of the 500 Club, is planning to do with his collection of demons and their coinciding sigil coins.
The clues soon lead them to shocking implications for all of demonkind and their masters.
While Ellie suspects Theo of having connections to Alfie and potentially his death, chaos unexpectedly ensues, building to a truly demonic confrontation!
