Hazar and his sister, Dorma, convince the Drule commander Borgam to meet with the Alliance to discuss peace. Borgam finds the Sea Team exploring a prehistoric planet, and makes contact with Commander Hawkins. Hawkins and Borgam meet face to face, and it seems like Hazar's dream of peace might still come true. However, could this really be the Drule's most involved treachery to date?

A series of letters from home reaches the Voltron Force, and for some reason this sends Chip into a deep depression. The Voltron Force needs to mobilize, but Chip is nowhere to be found. Hawkins sends out the incomplete force, but they can't form Voltron. It's up to Lisa to find Chip and convince him he's an important member of the team before the others are blown away by a Drule trap!

As Hazar makes another desperate attempt to arrange peace between the Drule Empire and the Alliance, the Drule council sees this as an excellent way to trap Voltron. Setting up a fake peace conference, they ambush the Air Team when Jeff flies his men in to scout out the meeting place. Jeff's team ends up trapped in a cavern, and the entire planet is set to explode!

Jeff, Krik, Cliff and the rest of the Voltron Force are camping on a new planet while the Explorer is down for repairs. The Drule Empire sends a fleet after them, jamming their communications and attacking. Krik and Cinda are separated from the others, so forming Voltron is impossible. The Explorer is pinned down and even Hawkins is ready to admit defeat… until the arrival of an old friend!

Jeff leads the Air Team into a Drule Robeast factory, but he's wounded by an enemy attack. Krik leads the team in his place, but he finds that the factory is actually a trap set by Marshal Keezor. They set explosives at the base's main reactor, but they have no way of getting out themselves. Colonel Carver is determined to save the Voltron Force, even if it means sacrificing his own ship.

Jeff and the Voltron Force are sent to attack a Drule command base, but it's well protected by an impenetrable asteroid belt. In addition, the enemy has set up a field of space mines. Luckily, before Voltron can fly into the trap, one of the Drule commanders becomes impatient and launches a pre-emptive strike. Jeff takes the chance to disrupt the Drule's plans. It won't help if he can't get past the asteroids.

Drule saboteurs manage to disable Voltron's energy supply system, making it impossible to form the super robot. The empire takes full advantage of this, sending a fleet to Earth to stage a direct attack on Galaxy Garrison high command! The Voltron Force can only watch helplessly as enemy ships bombard Earth's surface directly. Carver's fleet rushes to help the Explorer, so the energy system can be repaired.

Hawkins lands the Explorer on planet Dema for some rest and relaxation, not realizing the planet is a hidden Drule slave base. The Drules ambush them, and a terrific battle unfolds. Seeing the chaos, the slaves decide to stage a revolt against their dangerous masters. Now Voltron has to protect the Explorer, defeat the Robeast and save the slaves, all at the same time.

The Voltron Force is attacked near planet Eldora when the local people mistake them for the Drules. Jeff is taken prisoner and tries to reason with them, but a nearby Drule commander realizes what's going on and demands Jeff's release, insisting he is one of the Drules. Jeff has no choice but to escape on his own, or the team won't be able to form Voltron in time!

With the Explorer undergoing repairs after the last battle, Nerok launches an attack on the Galaxy Garrison’s space station. The Alliance crew defends the station admirably, as both Hawkins and Carver desperately try to get their teams there in time. However, when a Robeast gets inside the station itself and begins to wreak havoc, it looks like they’ll be too late.
