Plot Summary

In 2009, American geologist Adrian Helmsley meets his friend, Doctor Santam Tsurutani, in India. Santam has discovered that neutrinos from a massive solar flare are acting as microwaves, causing the temperature of the Earth's core to increase rapidly. Adrian informs White House Chief of Staff Carl Anheuser and US President Thomas Wilson that this will instigate a catastrophic chain of natural disasters. At the G8 summit in 2010, other heads of state and heads of government are made aware of the situation. They begin a secret project intended to ensure humanity survives, choosing 400,000 people to board a series of gigantic ships to be constructed in the Himalayas. To help fund the venture, additional individuals are allowed to purchase tickets for one billion euros apiece.

In 2012, Jackson Curtis is a writer in Los Angeles who works part-time as a limousine driver for wealthy Russian businessman Yuri Karpov. Jackson's ex-wife Kate and their children Noah and Lily live with her boyfriend, plastic surgeon and amateur pilot Gordon Silberman. Jackson takes Noah and Lily on a camping trip to Yellowstone National Park, where they meet Charlie Frost, a conspiracy theorist living as a hermit and hosting a radio show from the park. Charlie believes a theory that suggests the Mayans predicted the world would come to an end in 2012, and claims he has knowledge of a secret "space ship" project and possesses a map of their location. The family returns home as cracks develop along the San Andreas Fault in California and earthquakes occur in the San Francisco Bay area. Jackson grows suspicious and rents a plane to rescue his family. He collects his family and Gordon when the Earth's crust displacement begins and they escape Los Angeles as it collapses into the Pacific Ocean.

As millions die in earthquakes worldwide, the group flies to Yellowstone to retrieve Charlie's map. The group narrowly escapes as the Yellowstone Caldera erupts. Charlie, who stayed behind to broadcast the eruption, is killed by the blast. Learning the ships are in China, the group lands in Las Vegas, where they meet Yuri, his sons, girlfriend Tamara, and pilot Sasha. They join the group and secure an Antonov An-225, fleeing Las Vegas as it is destroyed. The group flies to China, passing Hawaii as it is obliterated by volcanic eruptions. Also bound for the ships aboard Air Force One are Anheuser, Adrian, and First Daughter Laura Wilson. President Wilson chooses to remain in Washington D.C. to address the world about the coming disasters. After surviving the collapse of the Washington Monument, he is then killed by a giant tsunami that sends the USS John F. Kennedy crashing into the White House. With the Vice President dead and the Speaker of the House missing, Anheuser appoints himself acting president.

Arriving in China in a crash-landing that kills Sasha, Yuri and his sons are taken to the ships, stranding the Curtis family, Gordon, and Tamara, who do not possess tickets. The group is picked up by Nima, a Buddhist monk. They sneak into an ark through its hydraulics chamber with the help of Nima's brother Tenzin, a welder for the ark project. Meanwhile, Satnam calls Adrian to inform him that an uncharted tsunami is engulfing India and heading towards the arks. Anheuser orders the arks sealed, trapping thousands outside. Adrian convinces the G8 leaders to let the remaining people board. As the ark's boarding gate is lowered and then raised, Yuri falls to his death getting his two sons aboard, and Gordon falls between the gears and dies. A large drill then falls and becomes lodged between the gears, preventing the gate from closing and rendering the ship unable to start its engines. The tsunami begins flooding the ark, drowning Tamara and setting the ark adrift. Jackson and Noah free the drill from the closing mechanism. The crew regains control of the ark, preventing a fatal collision with Mount Everest.

When the floodwater from the tsunamis recedes after 1 month and 27 days, satellite data shows that Africa rose in relation to sea level, and the Drakensberg mountains in KwaZulu Natal are now the highest on the planet. As three arks (ark 04, the American ark, 06 and 07) set sail for the Cape of Good Hope, Jackson reconciles with his family and Adrian starts a relationship with Laura. The movie ends with a view of the Earth and a geographically different landscape.
