Larry Daley, who manages the night exhibit where the exhibits come to life because of the Tablet of Ahkmenrah, is in charge of the presentation. But when the exhibits go awry, Larry finds himself in trouble.He learns the Tablet is corroding so he does some research and learns that Cecil, the former museum guard, was at the site when the Tablet was discovered. He tells Larry they were warned if they remove it could mean the end. Larry realizes it means the end of the magic. He talks to Ahkmenrah who says that he doesn’t know anything.
