What does Delta 3 send in the massive cargo ship?
Sometime in the future, Earth is recovering from "The Robot Wars" that devastated the planet seven years earlier. Most of humanity now lives on the Moon within a domed city called New Washington, but their survival depends on an anti-radiation drug called Raddic-Q2 which is manufactured on the distant planet Delta 3.
As scheduled, Delta 3 sends a massive cargo ship with a supply of the drug, but the ship crashes into New Washington's dome and causes widespread destruction. The colony leader, Senator Smedley, and science advisor Dr. John Caball, try to contact Nikki, the leader of Delta 3, but instead hear from Omus, the "Robot Master," Caball's former apprentice, and the newly self-proclaimed Emperor of that world. Omus states that the crash was a deliberate attack and he demands the people of New Washington recognize his authority as their leader, or else he will send more ships with an invasion force of robots under his control.
Smedley refuses to give into Omus' threats and Caball suggests launching the Starstreak against him – an advanced starship designed for both space exploration and defense of the Moon colony, but Smedley goes against the plan since the ship has yet to be fully tested. Caball boards the ship anyway, and prepares it for launch, during which he accidentally exposes himself to a dose of deadly radiation while in the reactor room.
With no time to obtain any of the radiation drugs, Caball calls his son Jason to help him pilot the ship. Tagging along are Smeldey's daughter Kim, and "Sparks," a teleporting pilot robot that Kim had salvaged from the wreck of the cargo ship and repaired. When they arrive, Caball convinces them of the urgency to stop Omus at all costs. They agree to help steal the Starstreak and set course to Delta 3.
