In Williamstown, Kentucky, you’ll find the Ark Encounter, a “life-size” creationist museum showcasing all the animals that supposedly boarded Noah’s Ark, including dinosaurs. With remarkable access to the park before its grand opening, the filmmakers delve into the broader framework supporting the creationist movement. They unravel the various elements that have led the museum to present its narratives as historical truths, while also highlighting those striving to correct the scientific record. In the midst of a culture of science denial and a powerful, well-funded corporation, three Kentuckians—a local geologist, a former creationist, and an atheist activist—struggle to counter the movement gaining traction in their state. At the same time, devoted believers work tirelessly to craft the realistic animatronics that will feature in the Ark exhibit.
