Andor

Five years before the Battle of Yavin, Cassian Andor travels to the industrial planet of Morlana One on the trail of his missing sister. While searching for her in a brothel, Cassian is antagonized by two Pre-Mor Authority security officers.

Timm, still suspicious of Bix's relationship with Cassian, reports Cassian to Pre-Mor Security, who issue a warrant for his arrest. Karn partners with Mosk, an equally dutiful Pre-Mor officer, to arrest Cassian. B2EMO informs Cassian and Maarva of the warrant. Cassian prepares to flee the planet.

Luthen Rael, Bix's buyer, arrives on Ferrix and meets Cassian in an abandoned factory. Karn and Mosk also arrive there with a dozen security officers. They confront Maarva, but she refuses to cooperate. Karn intercepts a transmission from Cassian to B2EMO, thus pinpointing Cassian's position.

Luthen takes Cassian to the planet Aldhani, asking him to join a sabotage mission there. Cassian is reluctant but eventually agrees. Luthen asks him to use a pseudonym among the rebels, and Cassian chooses 'Clem'. Vel, the rebel group's leader, introduces him to the rest of the group but keeps Luthen's involvement a secret.

On Aldhani, 'Clem' hides his past from his fellow rebels and is met with distrust from most of them, particularly Skeen. Taramyn trains Cassian and the other rebels for the planned heist. While traveling to the Aldhani Imperial garrison, Cassian reveals that he is a mercenary.

Aided by Gorn, the rebels successfully infiltrate the garrison by posing as an escort squad for Commandant Jayhold Beehaz, Gorn's superior. They take Beehaz's family as hostages and force him to give them access to the garrison's payroll vault. While loading the credits onto an Imperial freighter, they are caught by Imperial forces and Taramyn and Gorn are killed in the ensuing firefight.

On Coruscant, Karn starts a new job at the Bureau of Standards. As the ISB gains more draconian surveillance and punitive authority, Meero is challenged by Blevin for breaking protocol around accessing data about thefts from Imperial installations.

Cassian is brought to a prison on Narkina 5 where he spends every day working in monotonous heavy industry with hundreds of other prisoners. Vel and Cinta travel to Ferrix to search for him. When Maarva falls ill, Bix attempts to contact Luthen to ask about Cassian's whereabouts, but Luthen, worried about being exposed to anyone monitoring communications, does not answer.

Meero and an Imperial scientist named Dr. Gorst torture Bix for information and realize that Cassian may have been involved in the Aldhani attack. Meero fails to learn anything from Bix about Luthen. The ISB capture a Rebel pilot from Kreegyr's group, who reveals a power station on Spellhaus is set to be raided. Mon reunites with Vel, revealed as her cousin, and encourages her to keep a low profile while maintaining the facade of a rich and politically uninvolved young woman.

By breaking a water pipe and flooding his work floor, Cassian disables the floor's security system, allowing work crews there to overpower the few guards and escape. Kino uses the prison's intercom system to encourage other floors to escape and the rebellion sweeps through the entire prison.

Maarva dies, prompting a funeral ceremony on Ferrix, which Meero encourages in the hopes that Andor will attend. Vel informs Kleya about Maarva's death and learns of Mon's reluctant plan to marry off her daughter to secure funding through Sculdun. Mon's daughter Leida begins taking part in group gatherings related to Chandrilan culture and traditions, much to the distress of Mon and Vel. Karn also learns about the funeral from Mosk, and journeys to Ferrix.

Cassian returns to Ferrix for Maarva's funeral and learns of Bix's imprisonment. Dedra Meero and the local Imperial garrison prepare to use the funeral to take Andor alive for questioning regarding Axis, while Luthen plans—with Vel and Cinta's assistance—to kill Cassian using the Imperial ambush as cover. Mon Mothma continues being surveilled by the ISB, who succeed in stopping Kreegyr's attack but leave no prisoners, angering Meero.
