The Bridge on the River Kwai soldiers is scheduled to be the first to cross the bridge the following day, so Warden waits to destroy both. However, by daybreak the water level has dropped, exposing the wire connecting the explosives to the detonator. Nicholson spots the wire and brings it to Saito's attention. As the train approaches, they hurry down to the riverbank to investigate. Joyce, manning the detonator, breaks cover and stabs Saito to death. Nicholson yells for help, while attempting to stop Joyce from reaching the detonator. When Joyce is mortally wounded by Japanese fire, Shears swims across the river, but is himself shot.
