American Sinner is the first foray into reality programming produced by The Holy Broadcasting Network, an upstart religious broadcasting company founded by Ray and Bonnie Carlton of the Anaheim, California-based Son Ray Ministries. The show follows Cosmo and Mackenzie Carpenter, a quirky Evangelical couple as they try to ‘Save’ their rebellious, often offensive daughter, Tiffany. However, when Tiffany turns up pregnant, things take on an even greater sense of urgency. Will Cosmo and Mackenzie be able to save their daughter and grandchild before it’s too late—or will Tiffany forever remain an American Sinner?
