Animal instincts on a sheep farm on Mallorca. Estella is a Ca de Bestiar, a sheepdog unique to the Balearic island since the thirteenth century. Miquel, a shepherd, offers an intimate view of what makes this breed of dog so special. His work with Estella is a well-choreographed routine with mutual respect and a language few speak. The breed's status as working dogs may disappear within a generation.
