The Deprogrammer (2016)

A troubled deprogrammer retreats to a remote location with a young cult member, determined to break the psychological hold her dangerous sect has over her. Confident in his methods and convinced that every belief can be dismantled through logic and pressure, he begins an intense battle of wills designed to free her from the cult’s influence. But as the days pass, the girl refuses to crack—and the lines between manipulation, truth, and madness begin to blur.
