Somerset, 1911. The forces of war are building across Europe, but this pocket of England, where the rhythms of lives are dictated by the seasons and the land, remains untouched. Albert Sercombe is a farmer on Lord Prideaux's estate, and his eldest son, Sid, is underkeeper to the head gamekeeper. His son, Leo, a talented rider, grows up alongside the master's spirited daughter, Charlotte --- a girl who shoots and rides, much to the surprise of the locals. THE HORSEMAN tells the story of a family, a community, and the landscape they come from.
