A Spanish high school has a problem: the building is haunted by the spirits of five students who died in a library fire, and who simply refuse to leave. In desperation, the school hires Modesto, a former substitute teacher who amazingly can see dead people; Modesto quickly realizes that the ghosts’ reluctance stems from their needing to graduate, and so he starts preparing them for some truly final exams. One part The Sixth Sense, one part The Breakfast Club, and totally charming.
