John is in the sky with the Environment Agency in Cumbria to find out about a new line of defence in the battle against flooding, which involves restoring rivers to their original meandering routes. Anita talks to a rural farming community that lost its livelihood to foot and mouth disease, and the horse whisperer whose life was turned around by her love of the animals.
Matt pays a visit to a farm in Buckinghamshire at harvest time, where some old-fashioned methods are used to bring in prehistoric varieties of wheat. Ellie has news about the harvest at a government licensed crop of opium poppies and a scheme to preserve the harvest mouse.
