A group of old friends arrange to meet in a chalet in the Pyrenees for a reunion and to spend a short holiday together. The years that have passed do not seem to have undermined relations, but among the many entertaining anecdotes there is one dramatic episode which continues to oppress the group. Suddenly a strange incident changes their plans and isolates them from the rest of the world, without any possibility of communicating with the outside. In this tense and dangerous situation the relationships begin to crack up. Fin is a supernatural thriller based on the bestseller of the same name by the Spanish writer David Monteagudo, published by Guanda in Italy.
