What you're in for: The thriller is based on King's 1992 novel about a woman (Carla Gugino) whose husband (Bruce Greenwood) unexpectedly dies after handcuffing her to the bed in an effort to spice up their marriage, leaving her trapped in their remote lake house. Plagued by visions of past trauma and her dead husband (and what looks like a rabid dog), she has to fight for her life and her sanity.
Notable gore: The method she uses to finally get out of the handcuffs is so, so stomach-turning.
