Set in homage to classic 1950s sci-fi, this electrifying series kicks off with the vanishing of the revolutionary G-Reaction engines, signaling the start of humanity's harrowing demise. With demented extraterrestrial enemies intensively constructing a fleet of flying saucers for the ultimate invasion, teen prodigies Penny Carter and Billy Kimura unite with a covert alliance to thwart the alien assault that threatens to unleash catastrophic helmet worms and their cruel tentacles of destruction! Overcoming alien onslaughts and evading destructive beams won't come easy, but these brave youngsters can count on assistance from the skies, thanks to skillful pilot James and his guide, Cpt. Clayton, who enter the combat to fend off an unimaginable menace to mere humans!
