Plot

During the Korean War, a Navy fighter pilot must come to terms with his own ambivalence towards the war and the fear of having to bomb a set of highly defended bridges.

It is the Korean War and Lt. Harry Brubaker is a fighter-bomber pilot on the aircraft carrier USS Savo Island. A WW2 veteran and Naval Reserve pilot, he was drafted back into service from civilian life. This makes him quite resentful and cynical about the war. Now he has a dangerous mission to perform, and he is not sure he is up to the task.—grantss

U.S. Navy Lieutenant Harry Brubaker (William Holden) is a pilot who previously fought during World War II, went back to his civilian job as an attorney, and is now a recalled naval reservist further engaged in the Korean War flying jets from carriers. The film starts with him returning from a mission where his jet sustained battle damage and he has to ditch it into the bone chilling cold of the Sea of Japan.

Brubaker is about to freeze to death when a Navy rescue helicopter appears. The rescue helicopter that saves Brubaker is flown by an enlisted Naval Aviation Pilot (NAP), the eccentric green top hat-and-scarf wearing Chief Petty Officer Mike Forney (Mickey Rooney), with Forney's crewman AD2 Nestor Gamidge (Earl Holliman) jumping into the freezing water to hook Brubaker to the rescue harness.

Rear Admiral Tarrant (Fredric March), the carrier task force commander, lost his own son at the Battle of Midway during World War II and Brubaker's manner and bearing brings back memories of his lost son. The admiral finds the pilot is tired of war and just wants to return to civilian life to be with his family and the legal career he left behind. Nevertheless, they both agree to the necessity of seeing this conflict through to its conclusion.

A new mission is set. The target is a group of bridges used by Communist forces. Commander Wayne Lee, the Commander of the Carrier Air Group ("CAG"), is dedicated to his men, but Tarrant would rather see him dedicated to his mission. Lee had come to Tarrant with a complaint over the carrier captain's overuse of engines on tied-down aircraft during docking. However, when reminded that the captain would be writing his performance review, Lee backs down -- a weakness which prompts Tarrant to decide not to recommend Lee for promotion.

Brubaker is told that his wife Nancy (Grace Kelly) and children arrived in Tokyo on an unexpected visit and he is given a three-day pass during a port visit. Their reunion is interrupted when Nestor shows up at their hotel asking Brubaker's help in bailing Forney out of the guardhouse after a brawl with another sailor. Nancy, anxious to have her husband back home, is terrified to discover the signs of a man ready to crack from combat fatigue. Nancy is deep into thoughts of being left a widow. Tarrant will try to support her, although he, too, remembers how his own daughter-in-law had almost turned insane after losing her husband, Tarrant's son.

Back to the carrier, Lee presents to his pilots the air photos taken from a low pass over Toko-Ri. The flak is extremely dense and the pilots have to fly very low into the banks of the river while receiving fire from all sides. Brubaker gets sick after this briefing and believes his days are numbered. He is ready to write a letter to Nancy predicting his own death. Lee tries to boost the pilot's morale by asking him to stay behind if he feels he cannot accomplish his mission. Brubaker vows to do his duty.

The initial attack is on a series of bridges. Lee organizes two formations, the second one to be led by Brubaker. The results from the first attack are incomplete, so he orders the second group led by Brubaker to attack. Brubaker's team dashes in low and completes the destruction of the last bridge. Lee then directs the air group to attack a secondary target, an ammunition dump. As Brubaker completes the run, his fighter aircraft receives a hit that creates a fuel leak. Lee escorts Brubaker, guiding him back to the carrier, but the fuel loss will not allow Brubaker to overcome the last hill before the sea. He belly-lands onto a relatively flat area.

The rescue helicopter and his faithful friends Mike and Nestor land close by to pick him up, but North Korean ground troops arrive and machine gun the helicopter, killing Nestor and eliminating any chance of flying out of danger. Brubaker and Forney hide in a small ditch, defending themselves with carbines and pistols, but eventually are outnumbered and both are killed.

After getting confirmation from the U.S. Army that the three Americans are killed, Admiral Tarrant is shattered by the news and demands an explanation. Lee retorts that despite the losses, the mission was a success. Tarrant sorrowfully must accept that Lee has "matured", recommending him for promotion. The film ends with Tarrant alone, wondering where Brubaker and all the others under his command could have found the bravery to do what is asked from them. The movie ends with a famous quote: "Where do we get such men?
