Plot summary

In Burma during World War II, a group of British prisoners of war is commanded by the warden of the Japanese camp they're being held captive in, Colonel Saito, to build a bridge over the River Kwai. The senior officer of the capitulated brigade, Colonel Nicolson, conflicts with Saito over the order, which obliges the British officers to perform work on the bridge as well. As punishment, the officers and the colonel are locked away, and the demoralized men are sent off to work. Nicholson and the officers are after some time released by and put in charge of their men by a desperate Saito, who fear that the lackluster work morale of the prisoners may cause the bridge to not be completed in time, which would in turn force him to commit seppuku. After the change in authority, work seems to be going on the way, but unbeknownst to the two colonels, escaped former inmate US Commander Shears is leading a mission from Ceylon with the goal of blowing up the bridge on the River Kwai.—goddangwatir
