In this first episode, the farmers find themselves in a new location, a new time period and with a new team member. There is a new farmhouse to modernise, strict new rules to abide by and air raid precautions to contend with.The team begin by reclaiming badlands to grow new crops. Peter works with a blacksmith to design a special 'mole plough' to help drain the waterlogged clay fields. Ruth and Alex get to grips with a troublesome wartime tractor - and must plough through the night to get the wheat crop sown in time.On top of farmers' herculean efforts to double food production, their detailed knowledge of the landscape also made them ideal recruits for one of the war's most secret organisations - the 'Auxiliary Units', a British resistance force trained to use guerrilla tactics against German invasion.
