At a green bean plantation in Kenya, Jimmy learns how they grow the beans so straight for the supermarkets, and finds out what happens to the beans that don't make the grade. He also discovers the remarkable lengths that the farmers go to to stop the local wildlife destroying their valuable crop. At a Norwegian scallop farm, Matt braves the icy waters of the North Sea to join the divers harvesting scallops by hand from the sea bed. This sustainable farming method could be a model for the rest of Europe, but it needs a constant source of baby scallops, so Matt gets hands-on in the hatchery as he learns how to encourage a scallop to procreate. And Kate tries to unravel a mystery about Cornwall's most famous local delicacy: what exactly goes into a Cornish Pasty, swede or turnip?
