In this locked room, high‑concept thriller that's part The Guest List, part The Girl Before, a couple’s romantic weekend‑getaway is not what it seems.
When Ellie and her boyfriend Steven take their first trip away together, what starts as an idyllic weekend soon takes a darker turn, as it quickly becomes apparent that each of them harbors secrets—and that one of those secrets is deadly.
Ellie is an NYU grad student, timid but fiercely intelligent, and eager for the perfect weekend away with her boyfriend. Steven is a wealthy and privileged teacher at an elite Manhattan school. His and Ellie's relationship has caused envy among the private school teachers in his academic circle.
When they head away for a romantic break, they're both excited to get to know each other better, away from prying eyes. But when a snowstorm strands them in the house it becomes apparent that neither of them is quite who they say they are—and that one of them won't escape the weekend alive.
