The Sadhu is about one man's choice between his spiritual oath and his human instinct. When James Jensen, a down on his luck Englishman, is recruited into her majesty Queen Victoria's army and posted with his family in India in the summer of 1858, he begins a journey that will take him from being a simple soldier to a spiritual warrior. But faced with tragedy and his own impending execution at the hands of his evil commanding officer, James flees his military unit only to find himself lost deep in the jungle and at the mercy of a seeming band of Indian killers. But when their leader, Dadathakur, orders a reprieve and eventually allows James to join them on their attacks of the local Indian landowners that side with the British, James embarks on a dark path of violence in an effort to avenge the atrocities committed to his family.
