Another great adventure into history with more nasty guys and some super new good guys and gals to help out our night guard Larry Daley (Ben Stiller) at the museum. This time it is the Smithsonian Institute, where all our old heroes have been sent for storage while their old home is updated for computer generated exhibits. Unfortunately our little monkey friend, Dexter, has taken the magic tablet with him and has awoken the evil pharoah Kahmunrah, who imprisons everyone in a container until they give him the tablet. Larry turns up to save the day and is joined by flying ace, Amelia Earheart, Abe Lincoln, General Custer and a giant squid, to overthrow Kahmunrah and his pack of baddies, including Al Capone, and Napolean Bonaparte. Funny, funny, funny.
