The Herdmans – Gladys, Claude, Imogene, Leroy, Ollie and Ralph – are undeniably the worst kids in the history of the world. They lie, steal, cheat, bully and overall terrorize their small community. But this Christmas, they’re taking over their local church Pageant – and they just might unwittingly teach a shocked little town the true meaning of Christmas.

After a vintage Chucky doll turns up at a suburban yard sale, an idyllic American town is thrown into chaos as a series of horrifying murders begin to expose the town’s hypocrisies and secrets. Meanwhile, the arrival of enemies — and allies — from Chucky’s past threatens to expose the truth behind the killings, as well as the demon doll’s untold origins.
