Three years after Attack of the Clones, the Jedi are spread across the galaxy in a war against the Separatists. The Jedi Council dispatches Jedi Master Obi-Wan Kenobi on a mission to defeat General Grievous, the head of the Separatist army and Count Dooku's former apprentice, to put an end to the war. Meanwhile, after having visions of his wife Padmé Amidala dying in childbirth, Jedi Knight Anakin Skywalker is tasked by the Council to spy on Palpatine, the Supreme Chancellor of the Galactic Republic and, secretly, a Sith Lord. Palpatine manipulates Anakin into turning to the dark side of the Force and becoming his apprentice, Darth Vader, with wide-ranging consequences for the galaxy. The only hope for the galaxy is Anakin's own offsprings, the twin children born in secrecy who will grow up to become Luke Skywalker and Leia Organa.
