High school transfer Chrys Willet (Dafne Keen) found something unlikely left behind by her locker's prior user... a skull-shaped whistle of ancient Aztec origin. Her crew's ill-considered choices to mess with the arcane object discover that it can summon the user's destined death-complete with the exact means and circumstances-and they're left trying to find some way of escaping the inevitable. Old-school shocker co-stars Sophie Nélisse, Ali Skovbye, Michelle Fairley, and Nick Frost. 100 min. Widescreen; Soundtrack: English.
