Marshall, Gilbert and Amy are three children at the age of 12 who will perform a more comedic task. The three children will move a 3,000-year-old mummy back and forth, placing the mummy away from its place. It may turn out to be a real disaster, because if the mummy is not brought back to its place of rest by midnight on Halloween, it will turn into dust. These children must work together to restore the mummy's existence and keep it from being stolen. If the mummy is not returned to its normal place, it will be very difficult.
