Marvin Killgore is a meteorite hunter, collector and dealer. His hunts have taken him all over the world. In Siberia, he took his metal detector into the forest. On his way out, he saw tiger tracks covering his own. He tells Dick that the challenge is to not only find the meteorites, but to figure out how to get them home. Also on the show: a man finds a 3.92 white carat diamond on the ground. And, a corn maze that may just save a family farm.
