Timewatch (1982) : 16x6

When war broke out in South East Asia in 1941, one hill tribe - the Christian, English-speaking Karen - distinguished itself in the fight against Japan. Karen helped halt the Japanese, taught British Army regulars to fight in the jungle, and worked with Force 136 - the British sabotage unit immortalised in the fiction film 'The Bridge on the River Kwai'. Fifty years later they are fighting for their independence. Using newly unearthed archive material and documents, Timewatch tells why the Karen feel abandoned by the British and how they remain in a brutal civil war with the Burmese.
