A group of young people from As Neves, a Galician village in the mountains, are celebrating carnival. The next day, Paula, one of the girls from the party, disappears. The only trace of her is a video recorded the night before, which is shared among the young people. When a snowstorm hits, the internet goes down and the village is cut off from communication. As the hours pass, the teenagers are not only confronted with fear, but also learn what solidarity means.
