This episode comes from at Osterley Park in Middlesex, the site of the first Home Guard training school, to look back to the Second World War and a time when millions of ordinary men were prepared to die for their country.
Home Guard recruit Robert Brown comes face to face with his father as a Home Guard Company Commander; Dad's Army creator Jimmy Perry explains why he signed up to the Home Guard; and Ken Chambers shares us his own extraordinary stories from his time in the Home Guard, some of which could have been taken straight from Dad's Army.
