Paula, a bestselling horror novelist's widow, discovers his fiction was based on a terrifying alternate dimension he stumbled into through a labyrinth in the woods on their property. Right before his death, he warned her not to publish his final work in progress. However, Doug, his agent and literary executor, their best friend, urges Paula to get her husband's posthumous work into print. When an obsessive fan keeps telling her the stories are based on fact and she is in danger, she appeals to Doug for help. He insists they should publish the last book, while she's determined to obey her husband's dying wish. Meanwhile, they also fight against their long-suppressed attraction to each other. Doug once wanted to become more than a friend to her, and now that she's free, those feelings flare up again.
