The film Beyond the Next Mountain tells the true story of how a remote tribe (Hmar) in northeastern India became Christians, and how one of their tribe went onto translate the Bible into their language. Below is the first part of the movie. The complete movie is available at YouTube and through Netflix.

The following is from a website  that has more information about the history behind this movie. http://en.wikipedia.org/wiki/Rochunga_Pudaite) At the close of the 19th century, the British branded the Hmar people of northeast India as "the worst headhunters". In 1871, they beheaded over 500 British Soldiers.Then, in 1908, a missionary from Wales named Watkin Roberts, armed with a copy of the New Testament, arrived in the area where the tribal group lived. He lived under the same roof and taught the Hmar people about God, specifically the Gospel of John. Through that lone missionary, Chawnga, the father of Rochunga Pudaite, was introduced to the teachings of Jesus.

Chawnga and a few tribesmen believed in what they learned and became dedicated Christians. Chawnga believed that his son, Rochunga, was God's chosen instrument to bring the Bible to the Hmar tribe in their own language. Rochunga did indeed accomplish this task not only for his native language, but also for a number of other tribes

He has since become founder of Bibles for the World, an international ministry working with India and with a location in Colorado Springs, Colorado. The ministry focuses on Bible distribution, child sponsorship, and the India Children's Choir.

Rochunga Pudaite's biography is recounted in James Hefley's book God's Tribesman: the Rochunga Pudaite Story (Holman, 1977), Joe Musser's book Fire on the Hill (Tyndale House Publishers, 1998), and in the film Beyond the Next Mountain (which can be watched instantly onNetflix). Pudaite is the author of My Billion Bible Dream (Thomas Nelson, 1982) and The Greatest Book Ever Written (Hannibal Books, 1989).
