When Dink, Josh and Ruth went to the museum to see mummies, a woman stole the child mummy who died with his parents. Ruth found the child mummy in the girl's rest room, and a woman came out and walk right toward the tomb. So Dink, Josh and Ruth thought the woman is the thief and they followed her because she maybe went back to the tomb to steal something else. There are no people in the tomb and they got trapped in there, then they found a secret door and sleep in there because they are tired. Suddenly, they heard a noise and woke up. They opened the door a crack and peered out, and they see two thieves are stealing the mummy's treasure!
Soon their parents and officer Fallon and Dr. Tweed(the worker of the museum) came in and rescued them.
