Countdown Horror Movie Trailer

You's Elizabeth Lail Faces Down a Haunted App — Yes, an App — in the Countdown Trailer

What if an app could tell you the exact day, exact minute, exact second you were going to die? Would you be brave enough to look? That's essentially the premise of Countdown, a new horror movie starring You's Elizabeth Lail.

In the freaky trailer for the film, which dropped on Friday the 13th (naturally), Lail's Quinn is a young nurse who hears about the app after a patient claims his girlfriend died after downloading it herself. She decides to test it out, and is horrified to see she only has three days left to live. With the clock quickly ticking down, Quinn and her friends race to figure out a way to prevent death from coming to claim them before it's too late.

Watch the trailer for Countdown above before the film arrives in theatres on Oct. 25!
