In 1938 Egypt, a team of archaeologists discover the tomb of pharaoh Ahkmenrah, including a young Cecil “C.J” Fredericks, finding the Tablet of Ahkmenrah. The locals warn the group that if they remove the tablet from the tomb, then “the end will come.”Night at the Museum: Secret of the Tomb Movie Download.
In present-day New York City, Larry Daley remains the night guard of the American Museum of Natural History. He and the other exhibits help re-open the Hayden Planetarium. A new Neanderthal resembling Larry named Laaa is introduced, who identifies Larry as his father. Ahkmenrah shows Larry that the tablet is suffering from a corrosion, which later causes the exhibits to act abnormally, causing massive chaos at the planetarium’s reopening. Afterwards, Larry catches his son Nick, who plans on taking a gap year to sort out his life, throwing a house party.
Larry reunites with Cecil, now in retirement, and tells him about the tablet’s corrosion. Cecil remembers “the end will come” prophecy and realizes that it meant the end of the tablet’s magic, which will cause the exhibits to become lifeless. Cecil explains that Ahkmenrah’s parents, Merenkahre and Shepseheret, may be able to restore the tablet’s power but that they are located in the British Museum. Larry convinces the museum’s curator, Dr. McPhee, to let him ship Ahkmenrah to London to restore the tablet, convinced that McPhee knows its secrets. Larry and Nick travel to the British Museum, bypassing the night guard Tilly. To Larry’s surprise, his favorite exhibits at the American Museum of Natural History, Theodore Roosevelt, Sacagawea, Attila the Hun, mini-figures Jedediah and Octavius, and Dexter the capuchin monkey have come as well, and Laaa (who stowed away in the box) is left to stand guard while the others search the museum, the tablet bringing its own exhibits to life.
