In the mist-shrouded hills of rural England, shepherd Elias Crane has lived his entire life in quiet solitude, finding comfort in the rhythms of nature. But one October night, while tending his flock beneath a strange red moon, he witnesses something impossible—a silent procession of figures moving across the moor, carrying a shrouded burden. When a local girl vanishes days later, Elias becomes the sole witness to a mystery spanning generations. As he searches for answers, he uncovers his village's buried secrets and realizes the figures he saw may not be human at all—and they know he watched.
