A special show for the holidays, looking back on some of the biggest events, cultural hits and Christiane's best interviews this year. One year after the outgoing Biden administration struck a deal to bring him and four other Iranian Americans back home, Siamak Namazi, the longest held American in Iran, speaks with Christiane about his captivity in Iran's Evin prison, the torture he underwent and what it feels like to be free. Then, Christiane sits down with Hollywood legend Tom Hanks and his co-writer Christopher Riley to discuss their unique documentary "The Moonwalkers," capturing humanity's obsession with space travel. She also revisits an exclusive report from Ukraine, where she gained access to a medical evacuation train used by the Ukrainian army to transport wounded soldiers from near the frontlines to hospitals around the country. Afterwards, "True Detective" stars Jodie Foster and Kali Reis speak with Christiane about the latest season of the hit series released to critical acclaim. Oscar-winning actress Meryl Streep and former Afghan politicians, negotiator Fawzia Koofi and Dr. Habiba Sarabi, also join Christiane to talk about their new documentary called "The Sharp Edge of Peace," following the doomed efforts to negotiate with the Taliban. And finally, in a moving interview during celebrations marking 80 years since the D-Day landings in Normandy, 101 year old U.S. army veteran Jake Larson speaks with Christiane about the shared values he and his fellow servicemen fought for during World War II.
