Tad desperately sought the acceptance of his archaeological colleagues as one of their own, but his constant bumbling always seemed to get in the way. In an accidental misstep, he destroyed an ancient sarcophagus and unleashed a dangerous ancient curse that put the lives of his friends Mummy, Jeff, and Belzoni at risk. With everyone turning against him and only Sara offering help, Tad embarks on an adventure that will take him from Mexico to Chicago and from Paris to Egypt, in a quest to lift the mummy's curse and prove himself worthy of being part of the archaeological team.
