..To give the Federation one final chance to surrender after the X-3 is launched..
|..To find a way to reverse the terrible effects the X-3 is causing on Earth.
The Earth is in turmoil! The radical change in atmospheric conditions caused by Spectra's X-3 missile is tearing the planet apart. Zoltar contacts G-Force and Chief Anderson with another proposal... if they surrender now, he can still reverse the effects of the X-3. But if he doesn't have an answer in twenty-four hours, then the Earth will be left to be destroyed. Anderson realizes it is possible to reverse the effects, but they would need a huge missile... which they don't have. But Keyop and Jason know Spectra probably does, so they want to go steal theirs and use it. Anderson okays the mission.
In the Spectra base, Zoltar's men tell him that the missile they're working on is not yet complete. Without its computer brain, it is worthless. It will take at least two days to get it installed, but Zoltar doesn't accept that. He wants it done immediately!
G-Force gets a signal from Mark and the team rush off to pick him up. Disguised as Spectra soldiers, both Mark and Cronus have infiltrated the Spectra base where they're putting the final touches on the missile that can save Earth. As Zoltar makes an inspection, he recognizes Mark and Cronus, who shed their disguises and grab Zoltar. But just then, the Phoenix comes crashing through the base's wall and Zoltar manages to escape.
Cronus says he intends on piloting the missile to Earth personally. But Mark says he's in command and demands to be the pilot. Mark grabs Cronus, and Princess tells him to stop because Cronus is his father! Mark stops in his tracks and Cronus admits the truth to Mark, then picks up the G-Force Commander and throws him away from the missile. Cronus jumps on board and launches towards Earth. Cronus arrives on Earth and detonates the missile which almost immediately reverses the effects of the X-3.
Later at Center Neptune, Mark and Princess stop in to see 7-Zark-7. He reports to Mark that seconds before the missile detonated, an escape capsule jettisoned. Susan looked into it further and the escape craft was headed back to Riga. Mark's father not only saved the Earth, but he got away safely.
Jason can be, and is, put in
command of G-Force with Mark still missing at the beginning of the episode
