The film The Bridge on the River Kwai dramitised the WW2 story of the Thailand-Burma Railway, yet it was largely fictional. Allied P.O.W.s battled torture, starvation and disease to hack the 255-mile railway out of harsh jungle for the Japanese. Finishing in only 14 months, many never returned from "The Railway of Death". This programme interviews former P.O.W.s and guards to reveal what really happened and how the "collaborating" officer, Lieutenant Colonel Philip Toosey, was a hero, not a traitor. The Japanese did not observe the rules of war and it is almost impossible to imagine the horror and suffering endured by the Allied prisoners. Subjected to unbelievable cruelty over 100,000 men lost their lives having been starved, tortured and ravaged by a host of terrible diseases. In a land that was witheringly hot and besieged by monsoon, they were caught in a relentless cycle of cruelty and death.
