While working on his new book, author Colin May finds himself unable to distinguish between reality and imagination. Shortly after relocating to his new residence in the Hollywood Hills, he starts experiencing auditory and visual hallucinations, often waking to a mysterious, deep voice echoing from somewhere on the property. As Colin’s novel, a true masterpiece, becomes more intense, his imagination and fear begin to blur his sense of reality. Those close to him—his nephew, his agent, and his husband—struggle to help him regain his grip on the real world. However, the voices emanating from the house’s bomb shelter grow increasingly louder. As Colin confronts the turmoil within his mind, he completes the book’s final chapter, culminating in a dramatic and frightening encounter with a familiar figure in the bomb shelter.
