The story of the Ark of the Covenant goes back many centuries. According to the Bible, it was built by the Israelites at God's command 3,000 years ago to hold stone tablets engraved with the original Ten Commandments, then vanished 500 years later from Jerusalem--and from history. Host Adam Mastrelli guides us through an international investigation, where teams sift through evidence and hunt for physical clues to prove if the ark was real and to determine if it still exists today.
