Thousands of solar systems are threatening to leave the Galactic Republic. Senator Padmé Amidala strongly opposes the formation of an army to assist the beleaguered Jedi. After two attempts are made on her life, Anakin Skywalker, the young Jedi Padawan under Obi-Wan Kenobi, is assigned to protect her. While they retreat to a remote haven on Naboo, Obi-Wan makes a startling discovery that may mean war is closer than the Jedi and Republic imagined. A war that will change the fate of the galaxy forever.
