In December 2004, a father plans something special for his young sons—Christmas by the sea in Thailand. But when a sudden illness forces a last-minute cancellation, their lives are unknowingly spared. Years later, the now-grown son begins to have mysterious, vivid dreams of the hotel they never visited—its hallways, the waves, the screaming. But he’s never been there… has he? The more he dreams, the more he remembers until the past starts bleeding into the present, unraveling a haunting mystery.
