Jimmy McNichol stars as David, oldest son of the seemingly well-adjusted Bowers. When David disappears from his family to live with the Light of Salvation cult, sister Janet (Kristy McNichol) refuses to automatically side with her parents and dismiss the group. Young Janet tries to give her brother's judgement the benefit of the doubt, looking for her own answers, as her desperate parents consult a mind de-programming expert. Taut and edgy at times, the film shows how vulnerable young people get targeted by cults and their charismatic leaders -- only to turn into mindless drones.
