Synopsis:
Puzzled by strange robberies committed by ancient people, the authorities alert the Challengers of the Unknown. The Challs trace the robberies to Darius Tiko who has invented a time machine. Tiko escapes into time pursued by the daredevils.

Ace and Rocky return to ancient Greece to recover a stolen aircraft that could change history. They are not trusted by the Great Oracle and are forced to flee. They steal back the plane from the Greeks, but it crashes when damaged. The Greek army begins rushing the Challs to kill them.

In ancient Egypt, Prof and Red are forced into a labor camp. They escape and encounter Rhamis who possesses a stolen telescope. Rhamis is attacked by members of the Sorcerer’s sect. The telescope is destroyed, and the Challs head back to the time machine to pick up Ace and Rocky.

Reunited with their teammates, the Challs head to the 15th century where Nostradamus has been visited by Tiko. They learn how Tiko has journeyed to the future. The Challs follow.

Tiko has amassed future inventions to take over the 20th century. The future police take the Challs and Tiko into custody for being in a restricted area. The time travelers are then sent home without the future devices. The police have also rigged the time machine to self-destruct upon return to the present. The Challs take Tiko to the authorities to answer for his crimes.
