One night, a headteacher gets an unexpected call and is told that one of his pupils has attempted suicide during a study trip to France. This event will unleash a series of sudden changes in the protagonists' lives and its consequences will be gradually revealed against the background of the bucolic landscape of vineyards, and a rural school in which lessons that don't appear on any curriculum are learnt about evil, vengeance and violence. In this novel, the author, with many years of teaching experience, shows us how the effects of new technologies and the appearance of intercultural phenomena add enriching but also add conflictual elements, in this changing reality which struggles to make itself known in the classroom and in life.
