Studies show that almost 20 percent of Americans believe in UFOs. And, as the much publicized Heaven's Gate incident pointed out, some of these people will go to extreme lengths in the name of their belief. UFO CULTS AND GROUPS traces the history of Heaven's Gate and compares it to another UFO group, the Unarius Academy, looking for insight into this growing phenomenon. Why do people join these groups, and why do some abandon all logic and reason in doing so? Interviews with former and current members of the groups offer a first-person view of what they are like, and point out the vast differences among them. Some are truly cults, which indoctrinate members and force them to embrace new beliefs and behaviors, while others are simply people joined together by a common interest. From the tragedy of Heaven's Gate to the remarkable number of people who belong to UFO groups of all descriptions, this is a thought-provoking look at a "fringe" belief that may not be as far from the mainstream as most think.
