After reclaiming the Tomo Kyutama, the Kyurangers must wait for the Rashinban Kyutama to recharge in order to look for the next piece of the Argo and take their time continuing with their campaign against Jark Matter's forces on Earth. However, their next enemy is Scorpio, the Karo of the Scorpius System and Stinger's older brother, who uses his poison to transform his victims into zombies.

The Kyurangers track down the location of the Ho Kyutama, one of the components of Argo, on Planet Vela, whose people are suffering with the pollution caused by Jark Matter. Meanwhile, Stinger finally comes face to face with his brother.
