When his publishers tell him he owes them one last book, Edward Sheehan (Michael Madsen) has little choice but to isolate himself in a cabin on a New England lake. Though his fans have come to expect truly terrifying stories from the mind of Edward, they are unaware of the morbid method he takes to get them on paper. He fears the inner depths he'll have to reach in order to make it to the final chapter. With only himself and his demons, he slowly drives himself crazy as he creates the most sinister book of his career: Gabrielle.
