Heaven's Gate: The Cult of Cults - S1 E1

2. The Chrysalis

As the Heaven’s Gate "Classroom" begins, Bonnie and Marshall - who call themselves "Ti" and "Do" or "The Two" - enforce strict rules of no family communication. After Ti dies from cancer in 1985, a distraught Do briefly allows members to visit their families, and a few consider leaving the group for good. When the members return, Do becomes much more controlling - and opens the door to group suicide.

3. The Second Harvest

Using a popular sci-fi TV series to help bolster his teachings, Do encourages asexuality and individual submission for the benefit of the collective - and even initiates voluntary castrations. Having dwindled in number, the group starts recruiting again, but they’re met largely with derision and skepticism. Seeing this as a sign, Do begins planning their exit to the next level.

4. The Exit

The 1997 arrival of the Hale-Bopp comet spurs the group to prepare for their departure, though their plan to commit mass suicide goes undetected. After an anonymous 911 caller alerts the authorities, Heaven’s Gate, deemed the first "internet cult," becomes a media and pop culture phenomenon - but the suicides have a very different effect on those closest to them. Today, former members, loved ones, and experts reflect on the legacy of Heaven’s Gate, offering a chilling reminder that indoctrination can happen to anyone.
