Uma learns that a goblin saw the trident fall into the waters of the isle when the barrier briefly vanished. Everyone is looking for it; even if it isn't magic, it can be used to barter one's way off this accursed prison. Uma decides that it's time to put together a crew to work for her, hearing Captain Hook is hosting a race and will give the Lost Revenge to whoever wins. She joins the race, convincing Harry Hook to be her first mate; Uma wins the race and the ship, recruiting Gil and other rogues. Uma learns from her fellow employee at the shop that Yen Sid knows where the pieces of Ursula's necklace are; once it's re-completed, it will seek out the trident. Gil's research reveals that Yen Sid brought his intern, Sophie with him to the island when he relocated. Threatening to destroy Yen Sid's sorcerer's hat, Uma learns that the necklace is on the Isle of the Doomed.
Ben eventually discovers Mal's reliance on magic during a date, and she comes clean about her insecurities, causing a falling-out. Mal returns to the Isle, now ruled by her former rival Uma, Ursula's daughter, along with Harry and Gil, the sons of Captain Hook and Gaston. Mal visits hairstylist Dizzy Tremaine, Drizella's daughter, who restores her signature purple hair, remarking that she felt that Mal's blonde hair was unnatural. Harry discovers Mal's return and informs Uma.
Ben, Evie, Jay, and Carlos learn of Mal's departure and sneak onto the Isle to find her, but Gil recognizes them. Ben confronts Mal, who rejects his feelings for what she thought was both his sake and Auradon's. Ben leaves dejected, only to be captured by Uma. Mal and Uma arm wrestle for Ben and Fairy Godmother's wand, which Uma wins. Uma then orders Mal and her friends to retrieve the Fairy Godmother's wand or Ben dies. Carlos and Jay return to Auradon Prep, where they create a replica of the wand using a 3D printer. They are caught by Lonnie, Mulan's daughter, who blackmails them into letting her come, having previously been rejected from Jay's sports team based on her gender.
Gil walks out of the woods alongside Harry, standing beside Uma as they confront Mal. When Mal sarcastically calls Harry "Mr. Coat Hanger," Gil compliments the nickname, but Harry quickly shushes him. Later, as Mal challenges Uma, Gil agrees with Uma that they would never want to be like Mal, joining in as they speak in unison with Uma's voice.
Uma has grown bored with living under sea, away from her army of pirates. She tried numerous times to get the attention of her top henchmen Harry and Gil through the barrier, but no success. Deciding to try breaking the barrier around the island, Uma commands her magic with all her might; the only thing she succeeds in is giving off a loud scream from her frustration. Her sea witch magic simply pales in comparison to the magic of Fairy Godmother. Hearing angry rock music coming from below the seafloor, she finds a crack and uses her magic to shrink down to fit through; the source is Hades. Uma reveals that magic is leaking in through the cracks, allowing a spark of blue light to return to Hades' long-burnt out ember; she coerces him into a partnership to get back at Mal and open the barrier.
While leaving the Isle, Mal and the others are stopped by Uma, Gil, and Harry, who takes the Ember; they agree to help after Mal agrees to release all the children from the Isle. he ember could revive Audrey, but only in Hades' hands; Ben agrees to send for him, while Uma, Harry, Gil, and Celia plan to return to the Isle. Mal apologizes for lying to her friends and former rivals and they forgive her, realizing that she was just trying to do the right thing. Hades arrives and revives Audrey, but decries the double standard by which Audrey is immediately forgiven because she is not considered a villain.
