Carlos is a sociologist who intends to do a study on begging. His project is to provide thirty euros (every day for a month) to a beggar to study how it can influence in day to day. After searching for a possible candidate, Carlos finds Juancho (Juan José de Dios). But Carlos never could figure out who is really the person that is doing the study and how, little by little, will emerge to be human in the voluntary homeless Juancho original project.
