Plot[]
Three years after the events of the first film, Larry Daley has left his job as night guard at the American Museum of Natural History to start a company selling his own inventions on direct response television. He visits the museum and learns most of the exhibits will be moved to the Smithsonian Institution archives and replaced with holographic displays, but the Tablet of Ahkmenrah will stay behind, leaving the departing exhibits without the ability to come to life at night.
Later, Larry receives a panicked phone call from miniature cowboy Jedediah, who explains that Dexter the monkey brought the tablet to the Smithsonian, where they are under attack by Ahkmenrah's older brother Kahmunrah. Larry travels to Washington, DC and poses as a night guard to sneak into the archives, where he finds his friends trapped by Kahmunrah, who plans to use the tablet's powers to conquer the world.
Aided by General George A. Custer, who is captured, Larry is joined by Amelia Earhart. They evade Kahmunrah's soldiers inside the photograph of V-J Day in Times Square, leading Kahmunrah to enlist Ivan the Terrible, Napoleon Bonaparte, and Al Capone to retrieve the tablet. Larry is captured, but when the tablet fails to open the Gate of the Underworld, Kahmunrah traps Jedediah in an hourglass and gives Larry one hour to decipher the tablet's combination.
Amelia has fallen in love with Larry, and the statue of Abraham Lincoln at the Lincoln Memorial mistakes them for a couple as they reach the National Air and Space Museum. They encounter various figures from the history of flight, including the Wright brothers, a squadron of Tuskegee Airmen, and Able the space monkey, while a group of Albert Einstein bobbleheads explain that the combination is the value of pi. Napoleon, Ivan, and Capone's troops arrive, prompting Larry and Amelia to escape in the Wright Flyer.
They crash into the Smithsonian, where Kahmunrah uses the combination to open the gate and summon an army of Horus warriors. Miniature Roman general Octavius arrives with the statue of Lincoln, frightening the warriors back to the Underworld, and Amelia gathers an army of allies including Larry's friends and Custer, leading to a climactic battle. Larry helps Custer overcome his fear of repeating the Battle of Little Big Horn, while Octavius rescues Jedediah, and Larry recovers the tablet and turns Capone, Bonaparte, and Ivan against each other. Armed with his flashlight, Larry duels a khopesh-wielding Kahmunrah as Amelia reopens the gate, allowing Larry to banish Kahmunrah to the Underworld.
Flying Larry and the New York exhibits home, Amelia reveals that she knows she is only a wax figure of the real aviator, and she and Larry share a kiss before she takes off back to the Smithsonian. Two months later, Larry has sold his company and made an anonymous donation to renovate the Natural History Museum and extend its nighttime visiting hours when the exhibits are alive; believed to be animatronics and hired reenactors, the exhibits are now able to interact with visitors at night. Back in his old job as night guard, Larry hits it off with a visitor named Tess, who bears a striking resemblance to Amelia.
