Under the Banner of Heaven is based on Jon Krakauer’s book of the same name, and follows a devout detective whose "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".

The book was based on the true story and told the origin and evolution of The Church of Jesus Christ of Latter-day Saints alongside the double murder committed in the name of God by brothers Ron and Dan Lafferty, members of a very small splinter group called the School of Prophets.

Dustin, the husband of British Olympian Tom Daley and an Oscar winner for his screenplay for Milk, has been trying to adapt the book for over 10 years.
