With suicide among Utah’s LGBTQ teenagers climbing at an alarming rate, Believer follows Imagine Dragons lead singer Dan Reynolds as he takes on a new mission to explore how the Mormon Church treats its LGBTQ members. Directed by Don Argott (DeLorean, Batman & Bill, The Art of the Steal), the HBO documentary sketches out the singer’s early years as a faithful Mormon and, following his marriage to actress Aja Volkman, his dawning realization that his church’s doctrine is flawed.
