In 1941, a few days after the successful attack on Pearl Harbor, the Japanese army began to occupy the Philippine Islands. Five months later, the US troops who had stubbornly garrisoned had to surrender to the Japanese due to the shortage of munitions, food and medicine, and were forced to start the cruel Bataan Death March. The surviving American prisoners of war were thrown into concentration camps on various islands. On October 20, 1944, MacArthur led his troops to land in Barrow, fulfilling his promise that he would definitely come back when he evacuated, and began the US military's counterattack. However, the American prisoners of war under the clutches of the Japanese army were still struggling on the line of life and death. At the end of 1944, the American prisoners of war on Palawan Island were bloodily massacred. In order to prevent the recurrence of atrocities, the US military headquarters decided to rescue the American prisoners of war in the Cabatoan concentration camp, which was located 30 miles behind the enemy's front line and held a total of 513 prisoners of war. The prisoners of war had been under the cruel labor of the Japanese army for three years and were seriously ill or weak. The day of the Japanese army's humanitarian destruction is not far away. Although Major Gibson (Joseph Fiennes) suffers from malaria, he still tries his best to inspire the morale of his soldiers and look forward to the day of free fighting as soon as possible. Margaret (Connie Nielsen), the widow of a soldier who is a medical worker, also secretly transports black market medicines into the concentration camp through the Manila underground organization to provide timely assistance to the prisoners of war who lack medical care. On January 28, 1945, although the plan was not yet complete, the terrain was unfamiliar, hundreds of Japanese troops were stationed in the prisoner-of-war camp, and thousands of Japanese troops were entrenched less than two miles away from the prisoner-of-war camp, but with the support of the Philippine guerrillas, Lieutenant Colonel Henry Musi (Benjamin Bratt) and Captain Robert Prince (James Franco) led the 6th Ranger Battalion to boldly penetrate the enemy's rear and successfully completed the most successful rescue operation in American military history at a minimal cost of casualties.
