FX’s Under the Banner of Heaven, the original limited series inspired by the true crime bestseller by Jon Krakauer, follows the events that led to the 1984 murder of Brenda Wright Lafferty (Daisy Edgar-Jones) and her baby daughter in a suburb in the Salt Lake Valley, Utah.

As Detective Jeb Pyre (Andrew Garfield) investigates events which transpired within the Lafferty family, he uncovers buried truths about the origins of the LDS religion and the violent consequences of unyielding faith. What Pyre, a devout Mormon, unearths leads him to question his own faith.
