"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.
