When Hap and Leonard are called in on a strange request (subduing a meth-hopped hog) by a desperate young lady, they quickly learn this woman is part of a fringe group: The Hatchet Girls, who have pledged their allegiance to a crazed and grudge-bearing leader bent on bloody societal revenge. The timing couldn't be worse to be caught in such a vile, sticky wicket of a case: both boys are wrapped up in their domestic lives: Leonard is in the midst of wedding planning with fiancee, Pookie. And meanwhile, Hap and Brett are hard at work on their new home. Homemaking bliss will have to wait as Hap and Leonard are driven to stop the danger in its tracks and better understand the group's mission and the plans they have already set in place for helter-skelter esque mayhem.

Life changes, midnight sneaks, and dark encounters with misguided dames who yell "Chop, Chop," lead Hap and Leonard into one of their darkest adventures yet.
