Princess Allura puts the Paladins through training when they start to lose their focus. They'll need to cooperate to learn to form Voltron.

Shiro must draw on painful memories from his past when a massive evil robot threatens the peace in Arus, forcing the lions into action.

As one Paladin threatens to leave the team, invaders storm the castle and destroy its power crystal in an attempt to steal Voltron.

Hunk and Coran try to retrieve a new crystal from the Balmera while the rest of the team work to prevent Sendak from leaving the castle with Voltron.

The paladins leave Altea and embark for Balmera to fulfill Hunk's promise to Shay. En route, however, a distress signal waylays the crew when they go to investigate the signal's source.

Allura, Coran and the Paladins return to the Balmera to free the natives, but the arrival of a Galra ship could force Voltron into action.

Allura considers making a heartbreaking sacrifice to save the team when the castle mysteriously turns on them and seems them hurtling toward doom.

The team stops at an isolated and seemingly insignificant Galra space station and discovers how the empire is gathering its energy from the universe.
