The Bridges at Toko-Ri

Lieutenant Harry Brubaker (William Holden), a naval reserve officer, reluctantly leaves his wife (Grace Kelly) and children behind after he's called back into service. Soon Brubaker receives his orders: to bomb five bridges that are of vital importance to the enemy. Despite his unhappiness at being back in action and his doubts about U.S. soldiers risking their lives on such a dangerous mission, Lieutenant Brubaker puts his life on the line to make sure the effort is a success.
