The Rebel Alliance learns that the Empire is building a second Death Star and that the Emperor is on board overseeing its construction. The Rebels plan to destroy the station, but a deflector shield protects it from attack. Han, Chewie, Leia, Luke, C-3PO, and R2-D2 are sent to Endor to disable the shield. After being chased by Scout Troopers, they are befriended by the native Ewoks, who join their fight against the Empire. Han tricks the Stormtroopers into letting him into their bunker and shuts down the shield. Rebels and Ewoks battle the Stormtroopers, with Chewie arriving to help his friends in a captured AT-ST Walker. With the shield down, the Rebel fleet destroys the Death Star, ending Emperor Palpatine's rule.
