FX has revealed a new trailer for the Andrew Garfield-led event series adaptation ‘Under the Banner of Heaven.’

The limited series was inspired by Jon Krakauer’s true-crime bestseller of the same name. A devout detective’s faith is tested as he investigates a brutal murder that seems to be connected to an esteemed Utah family’s spiral into LDS fundamentalism and their distrust in the government.

Andrew Garfield will star as “Pyre,” an LDS elder who is committed to his Church and family but begins to question some of the Church’s teachings through his contact with a suspected murderer. Daisy Edgar-Jones stars as “Brenda,” a young faithful Mormon who is the victim of a brutal murder.
