It’s Halloween eve on Shelter Island, and the small town is preparing for a killer storm. But the dark clouds gathering over the island are bringing with them a curse one-hundred years in waiting. As the woods give birth to an ungodly and insatiable creature of fire, bones, and earth, three sisters must scramble to stay alive through the long dark night of the Hollow. For it’s not something you can kill. It’s only something you can try and survive.
Just when their separation is coming to an end, and Kyle and Sophia have recommitted to each other, Sophia is accused of assaulting her husband’s “friend,” Claire, a woman he slept with once. In reality, however, Claire is engineering a series of attacks against herself to frame Sophia and keep Kyle for herself. When the ruse falls apart, Claire makes a direct attack on her rival.
