Official description
Sabine leads a mission to free her father from the Empire, but finds that a past mistake has been resurrected with deadly consequences.

Prison raid
Sabine Wren, Ezra Bridger and Chopper are hiding in a trench on the planet Mandalore, watching an Imperial prison in the distance. There's been intelligence that Sabine's father, Alrich Wren, has been moved to the remote prison from the Mandalorian capital, Sundari. When Ezra asks why, Sabine explains that her father still has friends in the capital, so the Empire likely moved him here to cut him off from them. In another trench, Kanan Jarrus and Fenn Rau are also hiding, waiting for the attack. Ezra has been loaned a jetpack, and he's not sure how much use he's going to be with it. Sabine tells him that since he's a Jedi, he should "pick it up on the fly." Chopper unnecessarily attempts to explain the point to Ezra.

Sabine climbs out of the trench, and is spotted by the stormtroopers on guard. She takes out the Darksaber and ignites it, and Ezra and the Clan Wren warriors waiting in the trench climb out as well. Sabine gives a battle cry, and the warriors charge forward. During the fight, Ezra attempts to use his jetpack, and doesn't fare particularly well. The leader of the Imperial Super Commandos guarding the prison contacts the governor of Mandalore, Tiber Saxon, and informs him of the attack. Saxon informs the soldier that he is sending reinforcements, and that he is ordering the weapon be prepared. At one point, Sabine is knocked down, and some stormtroopers manage to stun and hold her at blasterpoint, and the leader of the Imperial Super Commandos orders Ezra and the other attackers to surrender. With excellent timing, three Mandalorian warriors in blue swoop in, the woman in charge stating that Sabine is too important to be captured, and the battle begins again.

The Imperials are swiftly routed, but it's discovered afterward that the prison is empty. The blue-clad warriors land, and their leader, after removing her helmet, explains that Sabine's mother Ursa Wren sent them as reinforcements, and that Ursa had found out that Sabine's father had been moved, but was unable to directly contact them due to Imperial jamming. Fenn Rau introduces the red-haired woman as Lady Bo-Katan Kryze, who is seen by many as the rightful leader of Mandalore. Bo-Katan explains that the Jedi made her the regent of the planet near the end of the Clone Wars, but that she lost her position after refusing to do the Empire's bidding. Sabine offers her the Darksaber, telling her that she should have it, and Bo-Katan turns it down, stating that she had her chance and that she is not her sister. Shortly after, Ursa and Tristan Wren arrive, having been contacted by Rau. Ursa reveals that they've found out that her husband is being transported to Sundari for a public execution.

Attack on the convoy
Sabine, Rau, Bo-Katan and Ezra wait above a canyon, observing the smoke of Ursa and Tristan's attack, intended to divert the prisoner convoy carrying Alrich Wren into their path. Meanwhile, Kanan talks to Hera Syndulla via hologram. Hera reminds Kanan that they can't stay very long on Mandalore, as it was difficult enough persuading Mon Mothma to let Kanan, Ezra and Chopper go there in the first place, as the Spectres are valuable assets to the Rebel Alliance. Kanan is somewhat perturbed by being referred to as an "asset", and diverts the conversation to asking Hera how she feels about his absence. Hera asks if they are still talking about the mission, and Kanan states that that depends. They sign off, Hera asking Kanan to stay safe.

The prisoner convoy diverts into the canyon, as planned. Rau scans it, and detects a single unarmoured passenger in the middle transport, which is the most heavily guarded. Sabine outlines the plan: one of them will sneak in and attack the middle transport after the rest of them cause a diversion. Ezra asks if this part of the plan has his name on it, and Sabine points out how bad he was with his jetpack. He counters that he's improving. The attack begins with Sabine leaping off the cliff, swooping in and attacking the scout troopers on speeder bikes. She strikes the windscreen of the middle transport with a paint bomb, which causes her father to realize she's present. As Sabine, Bo-Katan, Rau and Kanan attack the convoy, Ezra flies in from behind and grabs on to the middle transport, clinging to the underside and stabbing into the controls with his lightsaber. When one of the super commandos looks underneath, however, Ezra has already moved to the back of the transport, out of sight. During the attack, Sabine acquires a speeder bike, and Kanan fights stormtroopers atop the first troop transport.

Ezra finally gets inside the transport as it hurtles towards a cliff, and takes out the drivers and super commandos inside. Alrich asks if Ezra is with Sabine, and the Padawan responds affirmatively, before clarifying that he's not with her in the romantic sense. Ezra cuts Alrich loose and gives him his jetpack, explaining that he's better off without one. As the transport hurtles off the cliff, Ezra pushes Alrich out the door, and he flies up to the top of the cliff. Ezra leaps out the door, and uses a series of Force jumps up the three falling transports to reach the top of the cliff, where he nearly falls before being caught by Sabine. Alrich is happy to see Sabine, and the two of them quickly get into a discussion about art. Sabine contacts her mother to report that the rescue was successful. Ursa responds that the Imperial forces are in retreat, but that reinforcements have arrived: a single scout walker of an unusual design. Sabine, hearing a familiar sound over the comlink, panics and tells her mother and brother to get out of there, and the comlink cuts out. Horrified, Sabine takes off for the battle site, and the others follow on jetpacks and the speeder bike.

They arrive to find the disintegrated bodies and damaged armour of several Clan Wren warriors. When Ezra tells Sabine it's not her fault, she explains that it is, because this was the work of her weapon, the one she built at the Imperial Academy. She collapses over a pile of armour, crying, because she believes that her mother and brother are dead because of her actions, and her weapon.

Pursuit
Shortly, voices are heard from nearby, and Ursa and Tristan walk up. The Countess is visibly injured, and she explains that Sabine's warning gave her and Tristan enough time to take cover, as they were on the edge of the weapon's area of effect. Sabine is incredibly relieved, and runs over to them. However, the respite is short-lived, as Rau spots approaching Imperial super commandos. Fighting ensues as Sabine, Bo-Katan, Rau, Kanan and Ezra attempt to get the injured Wrens out of the area. The speeder bike is quickly destroyed, and Ezra notes that they've been cut off as three TIE fighters swoop in. Fortunately, a Gauntlet fighter belonging to Bo-Katan's people arrives, shooting down one of the TIEs, and everyone climbs aboard. As the Gauntlet flies into the upper atmosphere, the two remaining TIEs pursue, one landing a hit on the ship. Rau, piloting, notes that their weapons have gone offline. Sabine tells him that she can keep them aloft, but says that they can't take another hit like that.

Down in the hold, the bay doors open as Ezra tells Bo-Katan that they don't have any weapons. She responds that a Mandalorian with a jetpack is a weapon, and leaps out. Ezra, following, grumbles that he isn't Mandalorian and doesn't want to be one. Bo-Katan flies to one of the TIE fighters and grabs on. Ezra, meanwhile, hurtles about on his jetpack and winds up pressed to the windscreen of the other TIE, to the pilot's confusion. Bo-Katan opens up the hatch of her fighter and drops in a grenade, flying away as it explodes. Ezra is shaken loose from the other TIE, and as it flies off he manages to use his jetpack's rocket against it. The two of them fly back onboard the Gauntlet.

Sabine's creation
Saxon reports to Grand Admiral Thrawn, via hologram, about the test of the Duchess, showing him a video of the weapon being used against the Clan Wren warriors. They discuss the fact that the weapon turns Mandalorian armor from a strength into a weakness, by targeting the beskar alloy it's made of. Thrawn notes that the weapon does not have as great a range as he expected, which Saxon had been attempting to conceal. The Grand Admiral tells Saxon that the mind that designed the weapon is their best option for fixing it, and orders him to capture Sabine.

Bo-Katan demands to know why Sabine would make a weapon that would target Mandalorian armor, and Sabine explains that she was young and arrogant, seeking a challenge. She had destroyed the prototype and erased the plans before she left the Imperial academy, and states that the Empire must have rebuilt the weapon. Bo-Katan is also surprised that Sabine named the weapon after her sister, and Sabine reiterates her "young and arrogant" comment. Ezra, noting that Sabine's weapon targets the material the Mandalorians' armour is made of, asks why they don't just make their armour out of something else. Sabine, Tristan and Bo-Katan all stare at him, and Sabine explains that for Mandalorians, armour is a living legacy, and that her armour was originally forged 500 years before, and it carries the history of its previous owners with it.

Arriving at Bo-Katan's camp, Sabine does not receive a warm welcome, as she is called a traitor by the warriors there. Ursa, disembarking from the ship, announces that attacking Sabine will bring down the wrath of Clan Wren on the perpetrators. Sabine owns up to her past misdeeds, and explains that she wants to destroy her weapon once and for all. Planning the attack, it's decided that they will sneak aboard Tiber Saxon's Star Destroyer near Sundari, breaking into two teams: one to destroy the weapon, the other to erase the plans from the Imperial database. Kanan, Ezra and Chopper volunteer to erase the plans. Ursa offers to lead the other team, but Rau points out that she can barely hold a blaster. After the briefing, Rau informs Bo-Katan that he's surprised at how well she's responding to Sabine. Bo-Katan responds that she thinks Sabine has a lot of potential, and Rau agrees.

Dealing with the Duchess
After dark, the strike team approaches Saxon's Star Destroyer by jetpack, and in Chopper's case rocket booster. They slip into the hangar, and sneak through the crates and vehicles stored there. Once members of the team are spotted, a firefight begins almost immediately. Kanan, Ezra and Chopper depart the hangar in search of the databases while the Mandalorians stay and fight. The Duchess' power core is missing, so Sabine and Bo-Katan go to the upper level in search of it. Finding it, they are ambushed by Saxon, who wants Sabine to repair her weapon and bring it up to full capacity. Meanwhile, Kanan and Ezra fight stormtroopers while Chopper plugs in and begins erasing the designs. Ezra attempts to contact Sabine and realizes she's in trouble, so Kanan tells him to go help her. Sabine, after being shocked by the weapon, agrees to Saxon's demand and adjusts it. Saxon's subordinate, Hark, protests, so Saxon shocks him with the weapon as well. He himself is unaffected due to wearing Imperial armour. Saxon thinks everything is going as planned when Sabine tells him the weapon is at full strength, but she then activates it, revealing she has reset it to affect only Imperial armour, bringing down him and all the Imperial soldiers on the ship. Before she can use it to kill all of them, Bo-Katan talks her down, asking Sabine if she wants to fight with honour, like a Mandalorian, or cowardice, like the Empire. Sabine slashes the weapon with the Darksaber, breaching its power core, just as Ezra arrives. The three quickly flee, and gather up the rest of the strike team, as the weapon's explosion will destroy the Star Destroyer. The strike team exits the same way they came in, as Saxon's warship crumbles behind them.

Passing on the Darksaber
Arriving back at Bo-Katan's camp, Sabine tells her that she has proven she is the rightful leader. Bo-Katan is uncertain, but Sabine and Ursa tell her that there are people willing to follow her. Sabine opens the Gauntlet ramp, revealing a gathering of warriors, including representatives from many other clans. Warriors from clans Vizsla, Rook, Eldar and Kryze and Rau, the only survivor of the Protectors, tell Bo-Katan they are willing to follow her. Ursa adds in Clan Wren to the list. Bo-Katan finally accepts the Darksaber, and ignites it as the warriors kneel.
