By day, the 800-year-old temple known as Angkor Wat is one of Cambodia's most treasured national landmarks and tourist attractions but, by night, could it be ground zero for the region's angriest spirits? That's certainly the belief of many visitors to Angkor, a sprawling forty square mile complex of stone palaces, shrines, and ruins. In the center of this compound sits Angkor Wat, a 12th century structure originally designed as a Hindu temple, which now holds the distinction of being the largest religious building in the world. Equally impressive is the massive, 600-foot wide moat that separates Angkor from the mainland. Might this moat be an ancient attempt to keep the bad spirits away from the local people? Sounds like a case for Team Truth. A 36-year-old fisherman just vanished in Canada's Okanagan Lake. Even worse, this is but one in a string of disappearances reported to have occurred in the same area of this body of water.

The epicenter of Ogopogo sightings is the ominously named Rattlesnake Island, a small rock outcropping in the lake. Someone has to get to the bottom of this.
