When Cassian Andor's reckless search for answers about his missing makes him a wanted man, he returns to his home planet in hopes of selling illegal ship parts and reconnecting with his mother.

Cassian hurries to settle his affairs on Ferrix with friends and family as tactical forces close in on him, led by the conniving Karn, an agent driven by an obsession to preserve law and order.

The siege tightens as the armoured troops close in on the fugitive Cassian Andor. Desperate to escape arrest, Cassian contacts a mysterious but well-connected man who could provide him with money.

Out of options, Cassian joins a mission to infiltrate an Imperial garrison on Aldhani. On the city-covered capital world of Coruscant, agents of the Imperial Security Bureau start to piece together information regarding the disturbance on Ferrix.

Cassian must carefully navigate the distrust inherent in being the new member of a secret operation. As Cassian and the rebels prepare for a heist, they begin to suspect that they have a mole in their ranks.

With cover from a local festival, the Aldhani mission reaches a point of no return.
