..To cause space freighters to crash, eventually leading to Earth's surrender..

..G-Force must find Keyop who left alone to investigate a bigfoot in Tibet.

..........

While investigating reports of a bigfoot sighting in Tibet, two top scientists disappear. 7-Zark-7 tells G-Force to stand by in case they need to deploy to the area. But impatient as ever, Keyop heads there on his own to capture the bigfoot. In order to lead the team to him, 7-Zark-7 tracks Keyop’s progress.

At night in the Himalaya, the bigfoot rampages though his campsite. Keyop makes an emergency call to G-Force and Mark orders Tiny to head for his direction. The next morning at the campsite, two Spectra soldiers arrive. Keyop comes to, sees them and blurts out "Spectra!" The two soldiers contemplate what to do with him since he knows who they are.

G-Force arrives at the campsite where Jason finds Keyop's tent with all his gear but no Keyop. Just then, they receive a signal from Keyop who is washing dishes within the Spectra base. The Spectrans decided to use him for labor. Later, Keyop is repairing Spectra snowmobiles when one of the guards tells him he a new machine to fix. Keyop goes to fix it and finds that it is the bigfoot monster. The two guards enjoy a laugh over how scared Keyop is. Keyop says he’ll fix the bigfoot "Good." He then sends another signal to G-Force.

G-Force speed to Keyop’s position, but Spectra is waiting for them and they fire off barrages of missiles at the Phoenix from canyon walls. Mark is able to use the explosions from the missiles to trigger an avalanche that buries the Spectra base.

Keyop pilots the bigfoot into Zoltar's chambers and is joined almost immediately by G-Force, who smash into the chambers in the Phoenix. Zoltar attempts to get away, but is stopped when Keyop trips him with his bolos. Mark, Jason and Princess emerge from the Phoenix and Mark rips Zoltar’s mask off to reveal a mane of long blonde hair. Almost immediately there is a flash of blinding light which turns out to be the Spirit. He laughs at the paralyzed G-Force, revealing himself to be the true ruler of Spectra. He tells them they’re no match for his great powers and he will eventually succeed in conquering Earth. The Spirit's laughter rings in their ears as the team falls unconscious.

When the team wakes up some time later. Zoltar, the Spirit and the bigfoot are all gone. They wonder if everything was a dream or if they really saw Zoltar with long, blonde hair. Mark thinks it's too unbelievable for the leader of Spectra to be a woman, but he believes that he saw one for a second. Tiny finds the idea that Zoltar being a woman is laughable. As the team leaves the site, 7-Zark-7 explains that the base is buried and that the threat is over. But, he says that the mystery of Zoltar still remains.

Tibet still exists as a country

Zoltar could possibly be a woman

The Spirit is the true leader of Spectra's forces

Note: A production error is present in this episode when Tiny laughs in Mark's voice. The scripts call for Tiny to laugh as is shown on screen.
