A deadly May 2021 plane crash in Tennessee draws public attention to the Remnant Fellowship Church and its founder, Gwen Shamblin Lara. Some experts, neighbours, and former members believe Gwen's church is a dangerous cult.

In 2018, Gwen marries struggling actor and singer Joe Lara, raising questions about the couple's chequered past. With close ties to Remnant, Joe's legal team help wage a bitter custody battle for his young daughter.

When two Remnant members are charged with the murder of their child, allegations of abuse within the church begin to surface; another tragedy forever changes the trajectory of the Remnant's future.

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.
