A rural community in Spain welcomes its first ever resident medical practitioner. He is taken aback by the peculiar actions of the locals almost as soon as he makes his first acquaintance with members of the community. When he tries to inquire about the problem, the younger residents of the hamlet make fun of him, a man named Gonzalo appears to be some kind of leader, and he is invited to leave the village. All his questions get no answer. His next-door neighbor is a young woman of exceptional charm and beauty; she is also a member of the teaching staff at the local school. They hit it off right away and go on to cultivate a genuine connection that ultimately blossoms into love for one another. Regrettably, Gonzalo believes that the young instructor is "reserved" solely for him, and as a result, he reacts violently. In the meantime, the physician has uncovered the cause of that peculiar behavior. A number of drug addicts launched an assault on the community a number of years ago, while the traditional feast was taking place, in order to steal money and commodities. Fight broke out, and as a result, several individuals, including Gonzalo's son, lost their lives. From that point on, Gonzalo and a number of other people started their own "crusade" against drug users.
