Synopsis
The evil wizard Crom threatens a tribe of humans at the Alamo. They can protect themselves by using a sophisticated Guardian machine that utilizes flying robot drones that can disable the wizard's laser tanks. However, it blows a circuit and cannot be replaced as circuits are no longer produced. Their only hope is to infiltrate Crom's lair in order to use his moon dial, which sends them to Old Earth. In the 20th century, Thundarr, Ookla and Ariel are aided by a little girl named Samantha, who helps them obtain a fresh circuit. The trio return to New Earth and prepare for battle with Crom, but are glad they had a chance to see the preapocalyptic world.
