Some time after the events of the first film, Buster Moon is thriving with his new theater. However, he fails to impress talent scout Suki, who tells him he would not make it in Redshore City. Buster, encouraged by Nana Noodleman, reunites the singers who competed in the first film and takes them to the city. They sneak in for an audition with entertainment mogul Jimmy Crystal. Crystal is uninterested in Buster's original show pitch, therefore, Gunter pitches a space-themed musical which includes songs from Clay Calloway, a legendary rock star who has not been seen in 15 years. Intrigued, and assuming Calloway will be a part of the show, Crystal greenlights it, telling them to have the show up and running within three weeks. During production on the show, Rosita develops a fear of heights during rehearsal and is unable to keep on her role, which Moon begrudgingly gives to Crystal's daughter Porsha on his insistence while Rosita is delegated to a minor role. Meanwhile, Johnny has been assigned to work with top choreographer Klaus Kickenklober for his part in the show but senses that Klaus dislikes him due to his inability to dance. Johnny comes across a street dancer named Nooshy, who agrees to help him out. Meena has been cast in a romantic scene with Darius, a self-absorbed, famous actor. Having never been in love before, Meena is unable to get the feelings across during their scene. She later meets and falls in love with an ice cream vendor named Alfonso. Ash and Buster visit Clay Calloway to convince him to be in the show. He refuses at first, but Ash changes his mind. Back at the theater, Buster asks Porsha if she would like to switch roles with Rosita as she cannot act. Porsha misinterprets this as Buster firing her. Upon learning this, Crystal threatens Buster by nearly throwing him off his building before locking him in a closet. Suki frees Buster and warns him to get out of Redshore City, before Crystal can kill him. Ash arrives with the crew and Calloway, who advises Buster not to run and hide like he did after he lost his wife, Ruby. Buster then decides to have the cast and crew put on the show one night behind Crystal's back and has Miss Crawly get Porsha to rejoin them in the show, while Johnny calls his dad and his gang to come over and keep Crystal and his goons from interfering with the show. During the show, a jealous Klaus takes the place of Johnny's performance partner to try to undermine his number, but Johnny defeats Klaus with encouragement from Nooshy and finally earns Klaus' respect. Porsha performs a high energy song and dance number, earning the adoration of the crowd in spite of her father's attempts to stop the show, infuriating him. Meena visualizes Darius as Alfonso and performs a romantic duet with him. Crystal tries one last time to stop the show by dropping Buster off the top of the stage, which causes Rosita to overcome her fear of heights to save Buster. When the time comes for Calloway to take the stage, he claims that he is not ready. Ash leads the crowd in a rendition of one of Calloway's songs, and an apparition of his wife appears beside him, giving him the courage to perform. After the show, Suki has Crystal arrested by the police for his crimes. While Buster and his friends prepare to leave with Nooshy, Porsha, and Clay joining them, Suki stops them and tells them that a major theater wants to put on their show. As the cast puts on their first performance, Buster watches from the VIP section, proud to have succeeded in Redshore City.
