Friends don't let friends join cults.

In this one, Ian and Liv talk about a religious cult that began in the 1970s, "The Class," which barely survived for 20 years until the remaining 39 cult members, along with their leader, committed mass suicide in 1997. Eventually, this became cult became known as "Heaven's Gate," and has since become famous not only for their mass suicide, but the sheer absurdity of events that the cult leaders orchestrated during its span of two decades.

Spoiler Alert: The aliens don't arrive in Part 1.

Also, Liv gains self-confidence. Ian learns about the post office.
