Castle Rock is switching things up for its second season. 

Instead of serving as a sequel to Castle Rock Season 1, we will be getting a different tale set in the same town. 

But this tale is based on Stephen King's Misery novel, which was turned into a popular movie led by Kathy Bates. 

It serves as an origins story for Annie Wilkes, and Lizzy Caplan is taking on the lead role as the "budding psychopath."

Here's the official logline:

A psychological-horror series set in the Stephen King multiverse, Castle Rock combines the mythological scale and intimate character storytelling of King's best-loved works, weaving an epic saga of darkness and light, played out on a few square miles of Maine woodland.

The fictional Maine town of Castle Rock has figured prominently in King's literary career: Cujo, The Dark Half, IT and Needful Things, as well as novella The Body and numerous short stories (Rita Hayworth and Shawshank Redemption) are set in there.

Castle Rock is an original suspense/thriller - a first-of-its-kind reimagining that unites King's themes and worlds and brings together the author's most iconic and beloved characters.

In season two, a feud between warring clans comes to a boil when budding psychopath Annie Wilkes (Lizzy Caplan), Stephen King's nurse from hell, gets waylaid in Castle Rock. 

Tim Robbins, Paul Sparks, Yusra Warsama, Barkhad Abdi, Elsie Fisher, and Matthew Alan are also part of the cast of the highly anticipated second season.
