Each summer in the Galician town of Sabucedo, the young people of this rural parish take part in a tradition known as Rapas des Bestas - a festival, dating back 450 years, in which participants cut the manes of wild horses. The aloitadores, those responsible for restraining the horses while the cutting takes place, do so without ropes or sticks; relying on skills learned from an early age, and based on techniques passed down by the generations preceding them. In order to capture this unique and historically authentic tradition, London-based directorial duo Jose Otero and Louis Ellison (together forming Verso Films) struck out into the woodlands of Northern Spain, in search of one of Europe's oldest equestrian celebrations and the people who keep its flame alive.
