A deadly plane crash draws public attention to the Remnant Fellowship, a Christian-diet-program-turned-church, and its infamous leader, Gwen Shamblin Lara.

In 2018, Gwen marries struggling actor and aspiring country singer Joe Lara, raising questions about the odd couple's checkered past; with close ties to Remnant, Joe's legal team helps wage a bitter custody battle for his young daughter.

After a mysterious accident claims the lives of Gwen, Joe, and some of their inner circle, former Remnant members grapple with the leader's complicated legacy, and new voices come forward for the first time.

As the Remnant Fellowship fights to control the narrative, footage of a never-aired reality series pilot surfaces, casting new light on the ways Gwen shaped her image and the lives of those who followed her.
