Actress Lisa Hammond's grandfather is a mystery to the whole family!

Best known as market trader Donna Yates in EastEnders, actress Lisa Hammond wants to get to the bottom of why her paternal grandfather Harry Hammond never spoke about his experiences in World War II. She uncovers the moving story of the trauma he endured and his efforts to overcome it.

On her mother's side of the family, Lisa is reassured to discover many generations of London stock as she finds the countryside unsettling. But her relief is short-lived as, going further back, her investigations plunge her deep into rural Wales.
