Ezra, Zeb, Sabine, and Chopper head out to an old republic medical base in search of vital medical supplies only to be encountered by the Seventh Sister and the Fifth Brother. The Seventh Sister captures Ezra and interrogates him about the whereabouts of Ashoka Tano while Sabine is also captured by the Fifth Brother. Zeb and Chopper eventually rescue them and they all barely escape the inquisitors and head back to the rebel fleet.
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.
