On The Beach (novel) - Plot

Plot

The story is set primarily in and around Melbourne, Australia, in 1963. World War III has devastated most of the populated world, polluting the atmosphere with nuclear fallout and killing all human and animal life in the northern hemisphere. The war began with a nuclear attack by Albania on Italy and then escalated with the bombing of the United States and the United Kingdom by Egypt. Because the aircraft used in these attacks were obtained from the Soviet Union, the Soviets were mistakenly blamed, triggering a retaliatory strike on the USSR by NATO. There is also an attack by the Soviets on the People's Republic of China, which may have been a response to a Chinese attack aimed at occupying Soviet industrial areas near the Chinese border. Most if not all of the bombs had cobalt that was included to enhance their radioactive properties.

Global air currents are slowly carrying the lethal nuclear fallout across the Intertropical Convergence Zone to the southern hemisphere. The only parts of the planet still habitable are Australia and New Zealand, South Africa, and the southern parts of South America, although these areas are slowly succumbing to radiation poisoning as well. Life in Melbourne continues in a reasonably normal fashion, though the near-complete lack of motor fuels makes travel difficult.

People in Australia detect a mysterious and incomprehensible Morse code radio signal originating from Seattle, Washington, in the United States. With hope that someone has survived in the contaminated regions, one of the last American nuclear submarines, USS Scorpion, placed by its captain, Commander Dwight Towers, under Australian naval command, is ordered to sail north from its port of refuge in Melbourne (Australia's southernmost major mainland city) to contact whoever is sending the signal. In preparation for this journey, the submarine makes a shorter trip to port cities in northern Australia, including Cairns, Queensland and Darwin, Northern Territory, but finds no survivors. Two Australians sail with the American crew: Peter Holmes, naval liaison officer to the Americans, and a scientist, John Osborne. Commander Towers has become attached to a young Australian woman distantly related to Osborne named Moira Davidson, who tries to cope with the impending end of human life through heavy drinking. Despite his attraction to Davidson, Towers remains loyal to his wife and children in the United States. He buys his children gifts and imagines their growing older. At one point, however, he makes it clear to Moira that he knows his family is almost certainly dead, and he asks her if she thinks he is insane for acting as if they were still alive. She replies that she does not think he is crazy.

The Australian government provides citizens with free suicide pills and injections so that they can avoid prolonged suffering from radiation poisoning. Periodic reports show the steady southward progression of the deadly radiation. As communications are lost with a city it is referred to as being "out." One of the novel's poignant dilemmas is that of Peter Holmes, who has a baby daughter and a naive and childish wife, Mary, who is in denial about the impending disaster. Because he has been assigned to travel north with the Americans, Peter tries to explain, to Mary's fury and disbelief, how to euthanize their baby and kill herself with the pill should he not return from his mission in time to help. The bachelor Osborne spends much of his time restoring a Ferrari racing car which he had purchased (along with a fuel supply) for a nominal amount following the outbreak of the war.

The submarine travels to the Gulf of Alaska in the northern Pacific Ocean, where the crew determines that radiation levels are not decreasing. This finding discredits the "Jorgensen Effect," a scientific theory positing that radiation levels will gradually decrease due to weather effects and potentially allow for human life to continue in southern Australia or at least Antarctica. The submarine approaches San Francisco, California, observing through the periscope that the city had been devastated and the Golden Gate Bridge has fallen. In contrast, the Puget Sound area, from which the strange radio signals come, is found to have avoided destruction due to missile defenses. One crew member, who is from Edmonds, Washington, which the expedition visits, jumps ship to spend his last days in his home town. The expedition members then sail to an abandoned Navy communications school south of Seattle. A crewman sent ashore with oxygen tanks and protective gear discovers that, although the city's residents have long since perished, some of the region's hydroelectric power is still working due to primitive automation technology. He finds that the mysterious radio signal is the result of a broken window sash swinging in the breeze and occasionally hitting a telegraph key. After a brief stop at Pearl Harbor, the remaining submariners return to Australia to live out what little time they have left.

The characters make their best efforts to enjoy what time remains to them, speaking of small pleasures and continuing their customary activities. The Holmeses plant a garden that they will never see; Moira takes classes in typing and shorthand; Osborne and others organize a dangerous motor race that results in the violent deaths of several participants; elderly members of a "gentlemen's club" drink up the wine in the club's cellar, debate over whether to move the fishing season up, and fret about whether agriculturally-destructive rabbits will survive human beings. Towers goes on a fishing trip with Davidson but they do not become sexually involved, as he wants to remain loyal to his wife, a decision Moira accepts. Government services and the economy gradually grind to a halt. In the end, Towers chooses not to remain and die with Moira but rather to lead his crew on a final mission to scuttle the submarine outside Australian territorial waters. He refuses to allow his imminent demise to turn him aside from his duty to the U.S. Navy and he acts as a pillar of strength to his crew.

Moira watches the departure of the submarine from an adjacent hilltop as she takes her suicide pill, imagining herself together with Towers as she dies. When Mary Holmes becomes very ill, Peter administers a lethal injection to their daughter. Even though he still feels relatively well, he and Mary take their pills simultaneously so they can die as a family. Osborne takes his suicide pill while sitting in his beloved racing car.

Typically for a Shute novel, the characters avoid expressing intense emotions and do not mope or indulge in self-pity. The Australians do not, for the most part, flee southward as refugees but rather accept their fate once the lethal radiation levels reach the latitudes at which they live; most of them opt for the government-promoted alternative of suicide when the symptoms of radiation sickness appear.
