The mummy Imhotep needs the Manacle of Osiris to fulfill his quest to rule all mankind, but it's stuck on Alex's wrist, and only the Lost Scrolls of Thebes can remove it without destroying its power.

A clue about the scrolls in the diary of Alexander the Great takes the O'Connells into the Egyptian desert, where they encounter Imhotep, who is also searching for the same palace.

En route to Australia, the heroes crash-land on a small tropical island, summoning a long-dormant lava creature that pushes the local volcano toward eruption.

While in China, Alex befriends the young emperor of the Forbidden City, who promises to help find the lost scrolls - but instead accidentally unleashes a demon dragon.

A werewolf bites Rick when the family visits an abbey in Ireland, and Evy and Alex turn to the local townspeople for help.

The search is on for the three pieces of the Puzzle of Horus, which may lead the O'Connells to the Scrolls, but first they must battle Imhotep, Weasler and a giant sandworm.

Alex begins his Medjal training with Ardeth Bay and later learns that Imhotep is not only alive but is also planning to resurrect his long-lost love, an evil high priestess named Anck Su Namun.

A mortally injured Evy is brought back to life, but in the process the soul of Princess Nefertiri begins to overtake her.

Alex's new friendship with a archeological mercenary leads to tension in the O'Connell home and the discovery of family secrets.

Weasler gets a taste of power and turns it against Imhotep, hoping to beat everyone to a powerful and coveted artifact called the Trident of Voth.
