In the 90’s, a series of mass murders and “collective suicides” in France, Switzerland and Canada, reveals the existence of the Solar Temple Community, also known as OTS. Convinced of an imminent apocalypse, 74 persons are said to have committed suicide between 1994 and 1997 in mystical and macabre circumstances. How did these followers, for the most part educated and influent, allowed themselves to be dragged down to such atrocious deaths? Did they act consciously? Were they under the influence of their guru? Or were they brutally murdered?
