A gathering of lifelong companions gets together for an end of the week in a mountain lodge. Years have gone by but nothing appears to have changed between them. However, sneaking behind the chuckling and stories is a dim episode from an earlier time that keeps on tormenting them. An abnormal, unexpected occurrence modifies their arrangements, leaving them abandoned and without any line of correspondence to the rest of the world. On their way for help, the gathering begins to crumble, similarly as another regular request is revealed before their dumbfounded eyes.
