Overview:In this four-part documentary series, leading Hollywood actors undertake a fascinating journey into their family's past by re-tracing the footsteps of their grandparents during World War Two. We follow the moving, personal stories of Helena Bonham Carter, Mark Rylance, Kristin Scott Thomas, and Carey Mulligan as they travel to historic locations, from the beaches of Dunkirk to prisoner of war camps in Asia, to learn about the war their grandparents experienced. All of the actors have unanswered questions about the scars war left on their grandparents, and in each episode one of the actors explore how six years changed the lives of their family and the world forever while learning about the life and death decisions that their grandparents faced.
