On a diplomatic mission to the planet Rodia, Padmé; discovers that her old friend and fellow Republic senator Onaconda Farr has allied his planet with the Separatists. In exchange for food and resources for his people, Onaconda captures Padmé and promises to deliver her to the Nute Gunray. Sensing Padmé is in trouble, Jar Jar Binks disguises himself as a Jedi, and with the help of C-3PO, courageously fights to rescue his friend and fellow senator.

Ahsoka and Jedi Master Luminara escort the captured notorious Separatist leader Nute Gunray to Coruscant so he can stand trial for his crimes. However, they are unaware that Count Dooku has sent his assassin, Asajj Ventress, to free their captive. With the help of Senate Commandos, the Jedi have to thwart Ventress's efforts to free their prisoner, despite the traitorous plans of Senate Guard Captain Argyus.

Jedi Master Kit Fisto and his former Padawan, the Mon Calamari Jedi Nahdar Vebb, track escaped prisoner Nute Gunray to a remote world. Following Nute into a mysterious den filled with strange creatures, weapons, and war-time artifacts, the Jedi discover it is the trap-laden lair of General Grievous! Learning that Count Dooku has led the Jedi there in order to punish Grievous for his recent failures, the General is determined to prove his abilities and destroy the Jedi. Kit and Nahdar, along with a contingent of clones, must now fight their way past Grievous and his caretaker droid A-4D to avoid being caught in General's evil clutches forever.

During their own attempt to kidnap Count Dooku, Anakin and Obi-Wan discover that the Sith Lord has already been captured by pirates. Hondo Ohnaka and his gang of pirates hold Dooku captive in their den on Florrum, and hold him for ransom. It's up to Anakin and Obi-Wan to see if the offer is too good to be true.

Anakin and Obi-Wan have been duped and are being held for ransom along with Count Dooku by the pirate chief Hondo Ohnaka and his second-in-command, Turk Falso. While Anakin, Obi-Wan and Dooku unsuccessfully attempt to escape, the Republic sends the ransom via a special envoy, including Representative Jar Jar Binks. When Falso tries to steal the ransom from his boss by shooting down the shuttle, the only survivors are a squad of clones and Jar Jar, who as the most senior officer alive, has to take charge of the mission. It becomes a race against time as Jar Jar rushes to deliver the ransom to take custody of Dooku and save the Jedi.

Anakin and Ahsoka arrive at a pitched sky battle to help besieged Jedi General Aayla Secura. Anakin is gravely injured in the fight. Aayla and Ahsoka, along with the now-wounded Anakin, Rex, and the surviving clones, crash land on the uncharted grass-covered planet, Maridun. Forced to leave Anakin behind in order to save him, Aayla teaches Ahsoka why the Jedi have no personal attachments. They make their way to a Lurmen village. Their ruler, Tee Watt Kaa, explains that they're pacifists in this war and are not aligned with either side. Hesitant to have anything to do with the Jedi, Tee Watt Kaa agrees to help save Anakin's life.

The leader of the Lurmen, Tee Watt Kaa, refuses to shelter the Jedi from arriving Separatist forces, fearing that such an action would unnecessarily bring his neutral people into the war. Ahsoka, Aayla, the wounded Anakin, and the rest of the clones respect their wishes as they don't want to jeopardize the village with their presence, so they have to retreat into the wilds of the planet. Separatist Neimoidian General Lok Durd arrives to test a devastating weapon, which they plan to use on the Lurmen! Ultimately, the villagers have to decide whether they will lay down to the Separatists or fight with the Jedi to defend their village.

The Jedi, accompanied by Senator Riyo Chuchi and Chairman Cho of the nearby moon of Pantora, soon discover their clone troopers were attacked by a tribe of furry natives known as the Talz. Fierce beast-riding warriors, the Talz are very territorial and only want to be left alone. The Jedi manage to negotiate peace with the Talz chieftain, Thi-Sen, when greedy Chairman Cho breaks it by insisting the planet and the Talz are under his power. The resulting conflict escalates into war between the senator led clones and the Talz, with the Jedi in the middle.
