Three teams of relic hunters compete to find the most valuable artifacts as they travel to historic locations around the U.S. in this series, which begins in Fort St. Philip, La., with the search for Civil War relics.
Dirty tricks and high-tech toys are used when the teams arrive in Virginia to dig near the site of America's oldest European settlement.
A dig near the Antietam National Battlefield in Sharpsburg, Md., is marked by cold weather, malfunctioning equipment and bad luck.
The teams encounter bad luck at the start of their dig on the site of a Civil War battle in Louisiana.
