Not a Bite to Eat - S1.E21

Laura and Ethaniel drive to a small farming community called Granville. Information supplied by Byder tells them that Banning is searching for some kind of mineral deposit there. When they arrive they soon realize that whatever Banning is up to here it certainly has nothing to do with minerals. The only clue is a new breed of wheat being designed by Steelcut Farms, a company that seems to have a very high level of security for a simple wheat-producing farm.
