Ministry of Evil chronicles the life and crimes of Tony Alamo, who, together with his wife, became a born-again, fire-and-brimstone televangelist and cult leader. The two launched The Tony and Susan Alamo Christian foundation in 1969, which soon evolved into a cult that is said to still operate today. Together, by skirting the law and enforcing a code of silence among their followers, the Alamos came to wield unimaginable power, becoming millionaires on the backs of their believers. The new docuseries explores the cultural consequences of the Alamo empire and features rare archival footage, including an exclusive videotaped deposition with Alamo himself. It also weaves together interviews with the FBI agent who took Alamo down as well as cult survivors who have never previously shared their stories.
