Griff Rhys Jones never heard much about his father's time as a medical officer during World War Two, because his dad never really spoke about it. With just a few fragmented stories to work with, the comedian heads off to fill in the gaps himself, traveling to Ghana and the jungles of Burma with a 90-year-old veteran called Joshua keeping him company. He'll be finding out more about the Africans and Asians who fought for the Allies, and discovering what his dad got up to all those years ago.
