Forensic geologist Scott Wolter picks up the trail of the Ark of the Covenant, the gold-covered chest said to hold the Ten Commandments and the presence of God, last recorded in Jerusalem before its disappearance around 597 BC. Rather than searching Ethiopia or Egypt, the film follows Wolter's theory that the Ark crossed the Atlantic, tracing a chain of clues from the Hill of Tara in Ireland to carved stones and rock inscriptions in the Arizona desert. Wolter reads the geology of these sites alongside historical and religious sources, weighing whether ancient travelers could have reached North America centuries before Columbus and left a hidden sanctuary behind. The film moves between field investigation at these locations and interviews laying out the historical case, treating the Ark's American resting place as a live hypothesis rather than settled fact. It sits in the same territory as other fringe biblical-relic investigations, built on Wolter's geological readings and a trail of physical markers rather than direct archaeological proof.
