During the First Order's blockade of the planet Kashyyyk, Resistance members Beaumont Kin and Daz Crano were discussing strategies for locating Chewbacca within the Black Forest. Kin mentioned that Chewbacca had disappeared into the forest after a fellow Wookiee had whispered something to him. Kin expressed his confidence that Chewbacca had a plan and could handle the situation.
Meanwhile, deep within the Black Forest, Chewbacca and the porg named Terbus were attempting to evade detection by First Order stormtroopers searching for them. Their location was compromised when Terbus inadvertently stepped on a twig, alerting the stormtroopers. Chewbacca quickly concealed himself, trying to prevent Terbus from making any noise. Realizing the situation was dire, Chewbacca made a break for it as the stormtroopers opened fire. One stormtrooper pursued him on a 125-Z treadspeeder bike, but Chewbacca managed to knock the trooper off the speeder bike and commandeer it. Another stormtrooper on a speeder bike then charged at the Wookiee, but Chewbacca jumped off the speeder right before the two vehicles collided.
The Resistance initiated a search operation for Chewbacca, with Crano conducting an aerial search in her X-wing starfighter and Kin leading a ground team. Kin, after translating the Shyriiwook spoken by the local Wookiees, determined that Chewbacca was indeed searching for something of great importance within the forest. Nien Nunb subsequently discovered Chewbacca's bowcaster lying on the ground, leading the group to believe that Chewbacca was in far greater danger than they had initially thought.
Back in the Black Forest, Chewbacca and Terbus sought refuge beneath a destroyed walker as the stormtroopers continued their relentless search. Seizing an opportunity, Chewbacca ascended a wroshyr tree to survey the stormtroopers' movements. He observed that the stormtroopers were rounding up enslaved Wookiees, presumably as a contingency in case the First Order was unable to maintain its blockade. This enraged Chewbacca, who resolved to rescue them. At that moment, Crano flew overhead in her X-wing. Chewbacca and Terbus attempted to signal her, but she failed to spot them and continued on her course. Realizing that he would have to take action himself, Chewbacca leaped from the tree and swiftly neutralized the stormtroopers in his immediate vicinity. He then glanced down at Terbus, who gave him a salute, indicating his willingness to assist in the fight.
