While details are still scarce, here is the official description from Disney:

“The Andor series will explore a new perspective from the Star Wars galaxy, focusing on Cassian Andor’s journey to discover the difference he can make. The series brings forward the tale of the burgeoning rebellion against the Empire and how people and planets became involved. It’s an era filled with danger, deception and intrigue where Cassian will embark on the path that is destined to turn him into a rebel hero.”

On Disney’s website the series is described as a “tense nail-biting spy thriller.” The company has confirmed that the series will be twelve episodes long, which is longer than any of the previously released Star Wars shows. “You’re not going to recognize Cassian Andor in the beginning,” Luna said.
