This one-off special brings together British cult survivors, victims and family members, some of whom are talking for the first time about the trauma of indoctrination and escape from cults and fringe groups and how it's impacted their lives. The special steps inside the dark and sinister world of cults and manipulative groups, where 'abuse of power' and the 'desire to belong' dangerously collide. Contributors include survivors born or recruited into a cult or sect and experts, as well as the partner of one tragic victim of a British-based cult.
