In 1989 Montana, two friends on a camping trip stumble onto abandoned land tied to a secretive community preparing for the end of the world. When they take shelter in an isolated house, a mysterious string attached to a can reveals something listening beneath them. As night falls, strange sounds, unknown footsteps, and a familiar stranger blur the line between curiosity and danger. What begins as a harmless detour turns into a descent into the unknown, where unseen connections pull tighter and escape feels increasingly impossible.
