Mountaineer Joe Simpson, who told his story of near-death in the Andes in Touching The Void, travels to Myanmar (formerly Burma) to retrace the steps of his father Ian, who served with the Chindits - special forces who fought a guerilla war behind Japanese lines in 1944. Accompanied by explorer Ed Stafford, the first man to walk the length of the Amazon, and using the secret diary his father wrote, Joe experiences the challenging jungle conditions which made this one of the toughest campaigns of WWII.
