In this animated feature based on the action-packed thrillers, archeologists Rick and Evy O'Connell and their 11-year-old son, Alex accidentally get themselves involved in an ancient curse and have to save the world, which results in a lot of acrobatic fight scenes. Alex, foolishly gets an ancient Egyptian manacle stuck to his wrist, which won't come off without the power of the "lost scrolls." Unfortunately, the homicidal mummy Imhotep has again awakened, and he wants the scrolls too, as a way of accessing power over pretty much everything and everyone. The group must race against the mummy to get to the scrolls, locating clues along the way that point them in the right direction.
