“Ready or Not 2: Here I Come” picks up where we left off, with Grace smoking a cigarette on the steps of the family home, triumphant but traumatized. She needs medical attention, and when she wakes up in a hospital bed we soon learn how this new installment intends to keep the saga going. It turns out the Le Domas clan were but one of a cabal of world-ruling, Satan-worshiping families, and now that the family line has effectively ended, with only Grace left, there’s a potential vacancy in the cabal’s highest position of power — the “chair.” Because of an arcane set of rules, now all of the families must gather at a palatial manor for another night of hunting Grace, presided over by The Lawyer (Elijah Wood), Mr. Le Bail’s congenial right-hand man, who will make sure all the rules are followed.
