Doctor Who and Broadchurch actor Jodie Whittaker investigates her family history. On her dad's side, she looks into a romantic story she has been told about how her beloved grandmother Greta came to be given the middle name Verdun - also the name of a First World War battle fought shortly before Greta was born. The truth Jodie uncovers about Greta's eldest brother's sacrifice in that war is far more poignant than the family myth. On her mum's side, Jodie gets to the bottom of how her great-great-grandfather worked his way up from child labourer in a Yorkshire coal mine to mine owner, and how his sons kept the family's mines open during the biggest miners' strikes of the 1920s.
