Elizabeth Lail, who plays Guinevere Beck on stalker drama "You," just lined up horror film "Countdown."

The STX Films production is about a nurse who downloads an app that claims to predict exactly when you will die. When it tells her she has only three days to live (in, we suppose the voice of "The Ring"s Samara), she has to figure out how to save herself.

STXfilms chairman Adam Fogelson says of the actress, "Elizabeth Lail is an exciting young actress whose breakout performance in the wildly popular psychological thriller 'You' was a breath of fresh air. 'Countdown’ is a wholly original, scary, and fun script, and we’re thrilled to have found the perfect lead to bring this story to life for audiences around the world."

The script was written by Justin Dec, who will also direct.

Besides her role on the Lifetime series "You," Lail guest-starred on "The Blacklist" and "Once Upon a Time."
