"Come for a day or to stay!" beckons the maroon double-decker bus called The Peacemaker. One couple, searching for peace and a better life, did just that. In August of 2000, Tamara Mathieu and her husband gave up everything they had and joined the Twelve Tribes, a worldwide religious organization, with their 17-month-old son. They were just 23 years old. Fourteen years and three more children later, they fled back to "the real world. " This is the story of Tamara's journey to freedom. All Who Believed gives an honest look behind the scenes of the day-to-day life of a wife and mother in the Twelve Tribes, exposing the abuse and mind control that is a normal part of that life, as well as the controversial beliefs of this cult next door.
