S1·E26 Keenan's Raiders

Three members of outlaw gang Keenan's Raiders plan to meet in Bordertown to recover stolen gold they had buried years earlier. One dies of a heart attack on the stage, a second is found shot to death outside town. The third member has been wounded, and seeks medical attention from Marie. Jack and Clive discover that the two dead men are wearing identical belt buckles with a secret compartment, which conceals pieces of a map. Meanwhile, Marie has been taken hostage by the wounded man as he tries to dig up the buried gold.
