In this taut psychological thriller, the tragic death of their best friend Bea has splintered longtime friends Emilia, Finn, and Lucey, until Emilia convinces them to go on their annual camping trip to reconnect. But once they are alone in the woods, Emilia is haunted by the absence of Bea and provoked by Finn, the one person who witnessed her death. When they run into a solo hiker who inserts himself into the group, it tips the fragile balance of the trio to a boiling point. As things grow increasingly strange and distrust blossoms in the isolated forest, they suspect each other of terrible things, forcing them to call into question their friendship and own morality.
