Death is inevitable in Whistle, the latest horror from The Nun director Corin Hardy. The first trailer and poster make it clear: don’t blow it.

The cursed object nightmare hits theaters on February 6 via Independent Film Company and Shudder, promising a terrifying experience for fans of supernatural horror.

The film follows a misfit group of high school students who accidentally stumble upon an ancient Aztec Death Whistle. Once blown, the horrifying sound doesn’t just echo—it summons their future deaths, turning the teens into prey for their own fates.

As the body count rises, the friends scramble to uncover the whistle’s dark origins, hoping to stop the unstoppable chain of terror they’ve unleashed.

The cast features Dafne Keen (Logan), Sophie Nélisse (Yellowjackets), Sky Yang (Rebel Moon), Jhaleil Swaby (Supergirl), Ali Skovbye (Firefly Lane), Percy Hynes White (Wednesday), Michelle Fairley (Game of Thrones), and Nick Frost (Shaun of the Dead).

The script comes from Owen Egerton (Blood Fest), adapted from his own short story, while production is handled by David Gross (Room), Whitney Brown (The First Omen), Macdara Kelleher (Evil Dead Rise), and John Keville (Evil Dead Rise), with John Friedberg (Longlegs) among the executive producers.

Whistle is rated R for strong violent content, gore, drug use, and some language.

Prepare for a relentless, bone-chilling ride—because once the whistle blows, there’s no turning back.
