Sadie, Tom, Brett, and Amy are old friends from college, finally reunited for a long-overdue weekend at Amy’s family’s home in the mountains. But just as the weekend begins, a new app drops: BRUTL. It combs through your entire digital history and reveals the worst things you’ve ever said about the people around you. One by one, each friend gives in to using the app. What starts as a reunion turns into a reckoning, as buried opinions, brutal truths, and relationship-ending confessions come crashing to light.
