In 1985, Will Allen became a member of The Buddhafield, a Los Angeles area spiritual group. A recent film school graduate, Allen began to chronicle the group's activities that centered on their leader, a mysterious individual they called The Teacher, or Michel. Over time, the group's dark side began to surface, until finally, a shocking allegation against The Teacher tore the group apart - all in front of Allen's camera. This incredible archive of video footage became the basis for "Holy Hell".

Now, for the first time since he left the group, Allen turns the camera on himself and asks fellow ex-cult members to come to terms with their past and the unbelievable deceit they experienced.
