The shadows run free when Tut accidentally uses a scroll, this allows a shadow demon from the underworld to come to the overworld to eat the shadows, and Tut, Cleo, and Luxor have to get them back before the sun sets.
Tut befriends a couple of punks, and starts doing mischief around public. Cleo and Luxor tell him not to, but he does anyway. Because of this, he's brought to the Hall of Two Truths.
Tut cranks up the heat at the museum, allowing bills to pile up, so Behdety calls a salesperson to save money, little does he know that he is was stealing the museum artifacts, allowing Behdety to be framed and sent to jail.
