When Leonard inherits his hoarder Uncle Chester's house, it seems like the biggest problem Hap and Leonard will have is fending off the crack house denizens next door while they fix it up to sell. Instead, they find a child's skeleton in the crawlspace, along with bizarre collections of rotten porn, expired coupons and other clues that quickly lead to the conclusion that Uncle Chester, former security guard, and his irascible pal, an retired cop, were on the trail of something really nasty.
