The story starts with Jedi Master Mace Windu and the Jedi Battle Masters (Agen Solar, Kit Fisto, and Saesee Tiin) preparing to board a Jedi Gunship to the Chancellor's office. Just then Jedi Knight Anakin enters the hangar. Anakin says "Master Windu, I must talk to you." Mace says "What is it, Skywalker? We are in a hurry. We have just received word that Obi-Wan has destroyed General Grievous. We are on our way to make sure the Chancellor returns emergency powers back to the Senate." Anakin says "He won't give up his power. I've just learned a terrible truth. I think Chancellor Palpatine is a Sith Lord." Mace Windu replies in obvious surprise "A Sith Lord?" Anakin replies "Yes. The one we have been looking for." Mace Windu says questioningly "How do you know this?" Anakin replies "He knows the ways of the Force. He has been trained to use the dark side."Mace asks "Are you sure?"Anakin replies "Absolutely." Mace Windu tells Anakin "No. If what you told me is true, you will have gained my trust, but for now remain here." "Yes, Master." says Anakin obedientlyas he watches the Jedi leave in their ship.
Skip ahead to the Four Jedi walking into the chancellor's office
Palpatine says "Master Windu. I take it General Grievous has been destroyed then. I must say, you're here sooner than expected."
Mace says, igniting his Lightsaber "In the name of the Galactic Senate of the Republic, you are under arrest, Chancellor."
the other Jedi ignite their Lightsabers.
Palpatine says questioningly "Are you threatening me, Master Jedi?"
Mace says "The Senate will decide your fate."
Palpatine says with a burst of anger "I am the Senate!"Mace replies defiantly "Not yet!"
Palpatine stands, and from his cloak sleeve, a silver and gold cylinder drops, and he activates it, showing that It is a crimson Lightsaber and he spins toward the Jedi.
Palpatine says snidely "it's treason, then."
Palpatine cuts down Agen Kolar, then jumps and slashes Saesee Tiin's throat, Palpatine then stabs Kit Fisto in the Chest, Palpatine and Mace continue to fight.
Jedi Master Mace Windu and the Sith Lord fight their way down the hallway and into the main office area. Palpatine is able to use the Force to slam Mace against the wall, but he recovers before the Chancellor can cut him down.
Anakin lands his speeder, jumps out, and runs down a long corridor toward the Chancellor's office.
In the heat of battle, Mace cuts the window behind the Chancellor's desk, and it crashes away. Mace is forced out onto the ledge, which is twenty stories up. They fight over the precipice. Anakin arrives to see Palpatine and Mace fighting.
They stop as Mace forces Palpatine to drop his saber. Palpatine and Mace start yelling at each other.
Mace Windu says triumphantly "You are under arrest, My Lord."
Palpatine cries out "Anakin! I told you it would come to this. I was right. The Jedi are taking over."
Mace Windu says "You old fool. The oppression of the Sith will never return. Your plot to regain control of the Republic is over . . . you have lost . . ."
Palpatine says "No! No! You will die!"
Palpatine raises his hands, and lightning bolts shoot out. They are blocked by Mace's Lightsaber. Palpatine is pushed back against the window sill.
Palpatine says "He is a traitor, Anakin."
"He's the traitor. Stop him!" Orders mace
Palpatine says "come to your senses, boy. The Jedi are in revolt. They will betray you, just as they betrayed me."
Mace Windu yells with the stress of repelling Sidious's Lightning "Aarrrrggghhhhh . . ."
Palpatine: you are not one of them, Anakin. Don't let him kill me.
Mace, still screaming
Palpatine says "I am your pathway to power. I have the power to save the one you love. You must choose. You must stop him."
Mace grunts "Don't listen to him, Anakin."
Palpatine cries "Help me! Don't let him kill me. I can't hold on any longer. Ahhhhhhh . . . ahhhhhhh . . . ahhhhhhh . . . "
Mace pushes Palpatine out to the edge of the ledge. As the Jedi moves closer, the bolts from Palpatine's hands begin to arch back on him. The Chancellor's face begins to twist and distort. His eyes become yellow as he struggles to intensify his powers.
Palpatine "I can't ... I give up. Help me. I am weak ... I am too weak. Don't kill me. I give up. I'm dying. I can't hold on any longer."
Mace Windu says "You Sith disease. I am going to end this once and for all."
Anakin pleads "You can't kill him, Master. He must stand trial."
Mace Windu argues "He has too much control of the Senate and the Courts. He is too dangerous to be kept alive."
Palpatine "I'm too weak. Don't kill me. Please."
Anakin tries to reason with Mace "It is not the Jedi way . . ."
Mace raises his saber to kill the Chancellor.
Anakin: (continuing) "He must live . . ."
Palpatine pleads "Please don't, please don't . . ."
Anakin yells "I need him . . ."
Palpatine sobs "Please don't . . ."
Mace, drops his saber, and decapitates the Sith.
