Mountains of the Moon (1) - S2.E11

Tarzan comes across a party of religious pilgrims who are being led by Rosanna McCloud to their "Promised Land". To not shatter their dreams, Mrs. McCloud does not inform her followers that her husband, whom they regard as their Prophet, has just been killed, and she is unaware that the government trader who sold the group the land from a reclusive tribe had his own motives for doing so and never intended for the group to reach it. When Rosanna finally tells her group about the death of their leader, she and Tarzan also find that their money has been stolen.
