Admiral Ackbar has ordered all Republic forces to Jakku in the Western Reaches, where the Imperial Army and Imperial Navy have been reconvened, consolidated from Imperial fleets by Rax, among them her father's. The expected showdown is believed to possibly mean the end of the Galactic Civil War. The Republic Navy arrives, initiating the Battle of Jakku, while soldiers of the New Republic army are landed on the desert surface of Jakku. In the skies of Jakku, the Corvus receives a large number of distress calls from their sector. Iden and Shriv make their way to two X-wing starfighters while Del holds the Corvus and directs them towards the sources of the distress calls. They first land at a crashed Star Destroyer, where TIE bombers are deploying from and being used to harass Republic troops in the sector. Iden and Shriv fight against the stormtroopers defending the Star Destroyer and take it out before taking off to the skies again. They reinforce Captain Lindsey and his troops on the ground, who is on the march to Carbon Ridge to take out a mysterious Imperial research facility but has been intercepted by two AT-AT walkers and Imperial forces. Iden uses binoculars to indicate to the Starhawk Unity the coordinates of the AT-AT walkers so that it can launch orbital bombardments on them. The AT-AT walkers are taken out, and Inferno helps Lindsey and his troops take out the Imperial troops attacking them, allowing them to continue their advance to Carbon Ridge.
Iden and Shriv return to their X-wings and make it back to the Corvus, but they fall under attack from Imperial forces led by Hask, who pilots a modified TIE interceptor. After a hefty dogfight, Iden shoots him down, seemingly killing him, and decides to go after her father after spotting the Eviscerator, disabling communications with Del and the Corvus. She crash lands on top of the Eviscerator and fights her way through Imperial stormtroopers, making her way through a hole punched in the Eviscerator. As she makes her way to an elevator to the Star Destroyer's bridge, she hears an Imperial officer give a command to retreat to Counselor Rax and Admiral Versio order for evacuation before being cut off, learning that her father is still here. On the bridge, Admiral Versio gives the go for his right hand Imperial officer to leave while Iden confronts her father, telling him that he doesn't have to go down with the Empire. Garrick declines his daughter's rescue attempt. He tells her that Rax expects him to leave to, but he has also refused him. Garrick explains how he's given his life to the Empire and can scarcely believe that all that's left of it is being destroyed here. A Republic escort frigate crashes near the bridge of the Eviscerator, and Garrick falls into his daughter's hand but ultimately lets go. He tells his daughter that she is strong and urges her to find peace in her life as he resolves to go down with his ship. Realizing she cannot convince her father and seeking to get back to Del, Iden runs off as the Eviscerator begins to plummet to Jakku's sandy plains, the Star Destroyer exploding around her. She makes her way to an escape pod and launches towards Jakku.
