Septembre 1942, au large de Cape Town, en Afrique du Sud. Le "RMS Laconia", qui vient de quitter le port, fait route vers l’Angleterre avec 2 000 passagers à son bord ainsi que 1 800 prisonniers italiens. Les fumées du navire sont bientôt repérées par un U-Boot. Sa taille laissant supposer qu’il peut transporter des troupes, la décision est prise de le torpiller. Cela fait, le sous-marin ne quitte pas immédiatement les lieux. Découvrant le sort des prisonniers italiens, mais aussi de civils, le capitaine, se référant à un code d’honneur maritime, ordonne l’organisation du sauvetage, arbore une croix rouge dans l’attente d’un bâtiment français envoyé par Vichy. Mille personnes seront sauvées. Peu après, ce sous-marin sera coulé par les forces alliées tandis que l’amiral allemand Dönitz signera le "Laconia order" interdisant à l’armée allemande de procéder au moindre sauvetage.
Chanteraide est l'une des « oreilles d'or » de la Marine nationale, les spécialistes de la guerre acoustique. Son rôle à bord des sous-marins est essentiel. Pourtant il commet une erreur d'analyse qui manque de coûter la vie à tout l'équipage. En cherchant à la réparer, il se retrouve pris dans un conflit majeur auquel il pourrait bien être la réponse : de ses qualités professionnelles dépend l'ultime espoir de paix.
James Bond—MI6 agent 007 and sometimes simply "007"—attends the funeral of Colonel Jacques Bouvar, a SPECTRE operative (Number 6). Bouvar is alive and disguised as his own widow, but Bond identifies him. Following him to a château, Bond fights and kills him, escaping using a jetpack and his Aston Martin DB5.
Captain Hardt (Conrad Veidt), a World War I German U-boat commander, is ordered to lead a mission to attack the British Fleet at Scapa Flow. He sneaks ashore on the Orkney Islands to meet his contact, Frau Tiel (Valerie Hobson). Tiel has taken over the identity of local schoolteacher, Anne Burnett (June Duprez), who had been kidnapped by German agents. Hardt finds himself attracted to her, but Tiel shows no interest. The Germans are aided by a disgraced Royal Navy officer, the former Commander Ashington (Sebastian Shaw) who, according to Tiel, has agreed to aid the Germans after losing his command due to drunkenness, and Tiel implies that she has slept with Ashington to obtain his cooperation.

Set in San Francisco, California, down-on-his-luck Naval aviator Lt. Tuck Pendleton (Quaid) resigns his commission and volunteers for a secret miniaturization experiment. He is placed in a submersible pod and both are shrunk to microscopic size. They are transferred into a syringe to be injected into a rabbit, but the lab is attacked by a rival organization, led by scientist Dr. Margaret Canker (Fiona Lewis), that plans to seize the experiment and steal the miniaturization technology.
The United States and the Soviet Union have both developed technology that can miniaturize matter by shrinking individual atoms, but only for a limited amount of time, depending on how small the item is miniaturized.
In the closing days of World War II, Irishman Murphy (Peter O'Toole) is the sole survivor of the crew of a merchant ship, Mount Kyle, which has been sunk by a German U-boat, which then machine-gunned the survivors in the water. Murphy makes it ashore (to a missionary settlement on the Orinoco in Venezuela) where he is treated by a pacifist Quaker doctor, Dr Hayden (Siân Phillips).
L’Orsa Maggiore est le nom d'une escadrille spéciale de la Marine italienne qui effectue des missions de sabotage pendant la Seconde Guerre mondiale. Les hommes grenouilles qui la composent utilisent des maiali, des torpilles pilotables. L'action à Gibraltar est leur première mission. Les hommes grenouilles posent des mines sur trois navires anglais qui sont coulés ; pendant l'action, un homme grenouille et une femme agent secret de support à terre sont tués.
In 2174, the human population has exceeded the carry capacity of Earth, leading humanity to build an interstellar ark named Elysium. Its mission is to send 60,000 people on a 123-year trip to establish a colony on an Earth-like planet named Tanis. The passengers and crew are placed in hypersleep, with the crew on a hypersleep rotation to cover the entire journey. Eight years into the mission the ship receives a transmission from Earth in multiple languages: "You're all that's left of us. Good luck, God bless, and godspeed."
In 1961, the Soviet Union launches its first ballistic missile nuclear submarine, the K-19. The ship is led by Captain Alexei Vostrikov, aided by executive officer Mikhail Polenin. Polenin, the original captain, and the crew have served together for some time but Vostrikov's appointment is alleged to have been aided by his wife's political connections. During his first inspection, Vostrikov discovers the submarine's reactor officer to be drunk and asleep on duty. Vostrikov sacks the officer and orders Polenin to request a replacement. The new reactor officer, Vadim Radtchenko, arrives direct from nuclear school having just been fresh from the naval academy, annoying Polenin who thinks Vostrikov was too punitive on the former reactor officer who was competent despite his momentary lapse of judgment. Also, during the preparation period for the sub's launch, the ship's medical officer is killed when struck by an oncoming truck, and is subsequently replaced by the command's foremost medical officer, an army officer who has graciously offered himself in the submarine's time of need, but also privately admits to Vostrikov that as an army officer he has never been out to sea and suffers from motion sickness. During the K-19's official launch, the bottle of champagne fails to break when it strikes the bow; the sailors nervously glance at each other due to this customary sign of bad luck.
The British spy boat St Georges, which holds the Automatic Targeting Attack Communicator (ATAC), the system used by the Ministry of Defence to communicate with and co-ordinate the Royal Navy's fleet of Polaris submarines, is sunk after accidentally trawling an old naval mine in the Ionian Sea. MI6 agent James Bond, code name "007", is ordered by the Minister of Defence, Sir Frederick Gray and MI6 Chief of Staff, Bill Tanner, to retrieve the ATAC before the Soviets, as the transmitter could order attacks by the submarines' Polaris ballistic missiles.
L'équipage d'un sous-marin allemand sous le commandement du capitaine-lieutenant Liers est de nouveau en mer pendant la Première Guerre mondiale. Les hommes ont eu du mal à dire au revoir à leurs compagnes, mais le devoir les appelle. La mère de Liers a déjà perdu deux fils dans la guerre et redoute sa disparition.
Lieutenant Taylor (John Mills) and the rest of the crew of the submarine Sea Tiger are given a week's leave after an unsuccessful patrol. Hobson (Eric Portman) goes home to save his marriage, while a reluctant Corrigan (Niall MacGinnis) heads off to his wedding. Then the crew are called back to duty, much to Corrigan's relief, though he later has second thoughts. Sea Tiger is assigned the top secret mission of sinking Nazi Germany's new battleship, the Brandenburg, before she enters the Kiel Canal to begin sea trials in the Baltic Sea.
American David Ross (William Holden), a former tugboat captain now in the Canadian army, is hastily commissioned in the Royal Navy and assigned to rotating command of W88, a double-crewed rescue tug then in dry dock due to battle damage. His predecessor was a suicide. The slow, poorly armed tugboats bring in "lame ducks," freighters crippled near England by German attacks. The main danger is from U-boats and aircraft.
