Synopsis:
The Challs are brought to ancient Egypt through a strange portal. They witness June, who has already passed through the portal, being kidnapped. They also find statues with faces that resemble them.

An Egyptian guard informs them that June resembles the princess Tahasu whose likeness was carved on one of the statues. Someone when June passed through the portal, she had the Challs images carved, which allowed them to come through.

The team initiates a rescue mission to save June from Amenothoth, an evil advisor. He wants to learn the secret of the disc to bring future technology into his time and use it to rule the world. The Challs escape back through the portal with June. Once returned, they uncover the statues which still bear their likenesses.
