The Bridge on the River Kwai tells the story of three POWs who endure the hell of the Japanese camps on the Burma-Siam railway - Colonel Nicholson, a man prepared to sacrifice his life but not his dignity; Major Warden, a modest hero, saboteur and deadly killer; Commander Shears, who escaped from hell but was sent back. Ordered by the Japanese to build a bridge, the Colonel refuses, as it is against regulations for officers to work with other ranks.The Japanese give way but, to prove a point of British superiority, construction of the bridge goes ahead - at great cost to the men under Nicholson's command.
