Two former students of a strict religious school decide to go back during the summer vacation and make the teachers go through all the suffering that they imposed on both of them. An absolute masterpiece - One of the best Spanish films ever made! A scarcely known gem, this film deserves to be much more appreciated. The story is about religious education and its traumatic consequences on two ex-pupils, who now seek spiritual revenge on some former teachers... but the damage is done. The screenplay is simply superb. The cast is terrific (Hinojosa really steals the show, but Politti, Munoz, López Vázquez and the rest never done it better), and it is the best film ever directed by Antonio Hernández. A unique film not to be missed.
