Nell has always wanted to be an actor, but she doubts her ability. As a member of her school's theater program, she prefers working backstage. On the way to a contest, an unexpected blizzard strands her acting troupe in a creepy motel. Soon they meet a group of strangers from another high school--including the mysterious and handsome Knox, who insists they play the game Two Truths and a Lie. When it's Nell's turn, she draws a slip of paper written in unfamiliar handwriting:

I like to watch people die.
I've lost count of how many people I've killed.

Suddenly, a night of harmless fun turns into a matter of life and death. As guests start to go missing, it becomes clear that a murderer is hiding in their midst ready to strike again. In a room full of liars and performers, the truth is never quite what it seems. Nell is going to have to act like her life depends on it--because it does.
