The episode occurs midway through the total time length of the series. We see the end of the Battle of Muunilinst which started with the debut of the series, and the introduction of GeneralGrievous who will dominate the rest of the storyline.
On Hypori, Barrek's dead hand drops his holo-communicator, which is crushed by a robotic clawed foot. Thousands of B2 super battle droids encircle a crashed Republic Acclamator, firing their blasters at it until the clawed hand of the caped figure in front of them signals for them to stop. Inside the wreckage, Jedi Master Ki-Adi-Mundi wonders why the attack has ceased. Five other Jedi, wounded and weary, surround him: Shaak Ti, K'Kruhk, Aayla Secura, Tarr Seirr, and Sha'a Gi. As the Jedi wonder how they could have been defeated by mere battle droids, a voice calls out to them: GeneralGrievous, leader of the droid armies, deigns to grant them a noble death.
The sound of Grievous's approaching footsteps panics some of the Jedi, but Ki-Adi-Mundi urges them to remain calm. It's too much for Sha'a Gi, who charges into the open air where he is crushed to death as the metallic frame of General Grievous lands on top of him. Just as quickly, the general leaps out of sight, before dropping onto the remaining Jedi wielding two lightsabers. Spinning his torso around, Grievous easily holds off the four attacking Jedi, finally downing K'Kruhk. His clawed metal limbs get hold of Tarr Seirr and snap his neck, before hurling him and Aayla Secura across the chamber, followed by Ki-Adi-Mundi. Shaak Ti manages to hold off Grievous for some time, before she is hit by one of his spinning lightsabers and thrown into the wreckage. His own lightsaber held by Grievous's foot, Mundi uses the Force to pull one from Grievous's belt, which he ignites and raises into a guard. The two stare at each other for a moment before the droid general leaps at him, lightsabers angled for the kill...
On Coruscant, Master Yoda senses a disturbance in the Force: "Mmmm. Darker, the coming storm grows. I fear the dark cloud of the Sith shrouds us all." Listen(help·info)
This episode is more than twice as long as the previous episodes in the series at 7 minutes 15 seconds.
After Grievous fights the five Jedi initially, jumps to a wall and jumps again near them, Shaak Ti's lightsaber appears green though it is shown blue seconds before and later.
In this episode Grievous is depicted with five fingers and only uses two of his arms, although Grievous has six fingers and uses all four of his arms in Chapter 25.
In this episode, Grievous holds his defeated Jedi lightsabers on his belt. In Revenge of the Sith, they are held in his cape.
Originally, the last chapter was going to involve Anakin and Obi-Wan having to fight Durge. This was changed when George Lucas requested that they introduce General Grievous.
