"The Finder"

The remains of a maritime museum security guard are found in the Florida Everglades, after attempting to steal a 18th century nautical chart fragment that is used to discover treasures. To help solve the crime, Booth gets the help of Walter Sherman (Geoff Stults), a former U.S. soldier and Iraq war veteran, who has the ability to unearth anything. Along with Sherman, they are also assisted by his colleagues, Ike Latulippe (Saffron Burrows) and Leo Knox (Michael Clarke Duncan). During the case, Brennan tests Sherman's skills, while Booth has cold feelings about his former military comrade.
