Destination Tokyo is a 1943 black-and-white submarine war film. It was directed by Delmer Daves in his directorial debut, and the screenplay was written by Daves and Albert Maltz, based on an original story by former submariner Steve Fisher. The film stars Cary Grant and John Garfield and features Dane Clark, Robert Hutton, and Warner Anderson, along with John Ridgely, Alan Hale Sr., and William Prince.
On Christmas Eve, the submarine USS Copperfin, under the command of Captain Cassidy (Cary Grant), departs San Francisco on a secret mission. At sea, Cassidy opens his sealed orders, which direct him to proceed first to the Aleutian Islands to pick up meteorologist Lt. Raymond (John Ridgely), then to Tokyo Bay to obtain vital weather intelligence for the upcoming Doolittle Raid.
On the way, two Japanese planes attack; both are shot down, but one pilot manages to parachute into the water. When Mike (Tom Tully) goes to pick him up, he is stabbed to death. New recruit Tommy Adams (Robert Hutton) shoots the pilot, but because he was slow to react, Tommy blames himself for Mike’s death and volunteers to defuse an unexploded bomb stuck under the deck. When Mike is buried at sea, Greek-American Tin Can (Dane Clark) does not attend the service, which angers the other men until he explains that every Allied death causes him great pain. Meanwhile, Raymond, who lived in Japan, discusses how the Japanese people were led into the war by the military faction.
As the submarine nears Tokyo Bay, the Copperfin has to negotiate its way through protective minefields and a submarine screen. When a Japanese ship enters the bay, Cassidy follows in its wake. That night, a small party, including the ship’s womanizer, “Wolf” (John Garfield), goes ashore to make weather observations. Meanwhile, Tommy is diagnosed with appendicitis. “Pills”, the pharmacist’s mate (William Prince), has to operate following instructions from a book, using improvised instruments, and without sufficient ether to last throughout the procedure. The operation is a success, and “Cookie” Wainwright (Alan Hale) begins to prepare the pumpkin pie he had promised to bake Tommy.
Raymond broadcasts the information the shore party has collected in Japanese in an attempt to avoid detection, but the Japanese are alerted and search the bay. The Copperfin remains undetected, allowing the men to watch part of the Doolittle Raid through the periscope. After recovering Raymond and his team, the submarine then slips out of the bay following an exiting ship.
Later, the Copperfin sinks a Japanese aircraft carrier and is badly damaged by its escorts. In desperation, after long hours being attacked by depth charges, Cassidy attacks, sending a destroyer to the bottom and enabling the crew to return safely to San Francisco.
