Synopsis
After Dreylock and his army are defeated, the Rebel Knights feel like the threat has finally ended after three years. However, their celebration is short-lived when a new threat arrives on Earth to challenge our heroes. Cassie and Caitlyn leave both Santo Domingo High and the rest of the Rebel Knights in order to travel to Washington D.C. to get help to end the invasion.

Plot
In the beginning, the episode shows a recap from the beginning of the series and the previous episode.

In the continuation, the Rebel Knights struggle to fight back against the new enemy, but the ship's own fire power was far more powerful and advanced they Dreylock's. The ship's fire ball knocks Grover, Zoe, Jennifer, Matt, and Diesel off their feet and injures them. With five of the knights injured, they are forced to retreat.

Back inside the school, Natalie, Cleo, Cassie, Caitlyn, and Lori are treating their friends' injuries. Natalie states that their first battle with the new enemy was far much worse their their first battle with Dreylock. Aria, the knights' alien ally appears and is well aware of their battle against Treachera. She tells them that the villains they fought against since they became Rebel Knights were only the tip of the spear and that Queen Treachera and her army are an overwhelming and powerful foe. Diesel is angered by the fact that all of this time, their war against Dreylock was only the opening act for a more powerful force. Natalie keeps her optimistic hope that they will take out Treachera like they took out Dreylock. However, Aria tells her that the knights' fight against Treachera will not be that easy. She also tells them that their arsenal they took from Dreylock's soldiers, may be useless against the new threat. Grover agrees with Aria, as their first battle against her proved how powerful she really was.
