The HOAX is an examination of abusive power and lack of regulation in the homeowners' association industry; a business and quasi-government system whose key selling point is the protection of property values. The documentary follows an investigative reporter, homeowners, and HOA reform activists as they illustrate shocking evidence of financial and psychological hardships throughout Texas and Nevada. A few of these people, including the filmmaker, are the subject of adverse actions from various players in this quasi-governmental system.
