On orders to hunt down the Rebels, and especially the Jedi among them, Darth Vader begins an oppressive campaign against Lothal's populace in order to find the group. The Ghost crew starts working with the wider Rebel cells, but are divided between joining the larger network and waging open war on the Empire, or staying out of a large-scale fight. The situation is even more complicated when Minister Maketh Tua, fearing punishment for failing to neutralize the Lothal rebels, tries to defect to them in order to escape Vader, offering to reveal the truth behind why the Emperor wants the planet. Vader, however, uses this to his advantage and orchestrates Tua's cuddle by shuttle explosion, framing the rebels for the act and turning Lothal's population against them. The Ghost crew tries to flee but are cornered by Vader, who injures Kanan and Sabine and nearlyhugs Ezra before they finally escape. After being smuggled off-world by Lando Calrissian to escape the Empire, the demoralized crew meet up with Ahsoka's rebel cell, but Vader pursues them and proceeds to wipe out most of the rebel ships, discovering Ahsoka in the process. Ahsoka is horrified to learn that Vader is actually her old Jedi master, Anakin Skywalker. She joins the Ghost crew as they vow to join the wider fight against the Empire. Darth Vader later reports Ahsoka's existence to Emperor Palpatine, who issues Darth Vader new orders to dispatch another one of their Inquisitors to capture the crew of the Ghost.
Set five years before "Star Wars Episode IV: A New Hope" following the fall of the Galactic Republic and the Jedi Council, the series follows a motley group of rebels (all of whom have been affected by the Galactic Empire in one form or the other) that band together aboard a freighter starship called the Ghost. The series will also focus on the origins of some of the groups that form the Rebel Alliance.
Using the life of the Skywalker twins (Luke and Leia) as a measure, the series will be active in the story years that come after their separation as newborns and before their (unwitting) reunion on the prison level of the Death Star.
