According to Fisher, the story takes place between the Star Wars Rebels episodes "The Call" and "Homecoming."
Chopper wakes up on a planetoid, where he is about to be scraped for parts by Davil and Bidvel. Meanwhile on the Ghost, Hera Syndulla, Garazeb Orrelios, and Sabine Wren attempt to find the lost droid, but are attacked by an Arquitens-class command cruiser.
At first, Davil and Bidvel do not think Chopper will be worth much, but after realizing that the droid has rebel intel, they plot to sell the information to the Galactic Empire. Chopper is briefly able to escape, during which time he steals activation codes to reactivate the various droids around the scrap pile. Chopper is recaptured and Davil copies the information into their computers. As Chopper is about to be dismantled, the droids activate and begin to attack the two Xots. A B2-series super battle droid holds Bidvel at blasterpoint, but Davil is able to shoot one of the astromech droids. The super droid then shoots Davil with a stun blast and a droideka stops Chopper's destruction.
Soon after, the Ghost arrives, having escaped the Imperial ship, and lands. Syndulla promises to replace any parts Chopper lost, saying she will erase the data on Davil's computers that he stole. Chopper gives the rescued droids the idea to form a group to help droids, and they wish for Chopper to stay with them to lead them. Chopper refuses, preferring to stay with his friends, and the group of droids understands, saying that they hope they will meet him again.
