The Mandalorian and Grogu

Mandalorian bounty hunter Din Djarin, known as Mando, and his foundling Grogu work for the New Republic to hunt down neo-imperialist warlords of the former Galactic Empire. After a successful mission, Mando is tasked by New Republic commander Ward to find the mysterious warlord Commander Coin. The New Republic has been offered intel on his whereabouts by the Hutt Twins, siblings and successors to the deceased crime-lord Jabba, but only in exchange for rescuing Jabba's son and heir Rotta from the moon Shakari. Mando receives a new Razor Crest ship as pre-payment.

Mando reluctantly accepts the assignment, and upon arriving at Shakari discovers that Rotta is a popular gladiator in a fighting pit owned by crime-lord Janu. Rotta, desperate to step out of Jabba's shadow, enjoys his status as a self-made fighter and refuses to be rescued by Mando, saying that his next fight will repay his debt to Janu and set him free. Mando tracks Janu down and offers to buy Rotta's freedom, but Janu refuses, intending for Rotta's final fight to be a Dejarik match in which he will continue fighting monsters until death. With this new information, Mando returns to Rotta, who refuses to believe him, instead calling on security. Mando is subdued and must fight Rotta in the arena. He defeats Rotta, but surrenders rather than killing him. He tells Janu that this fight has fulfilled Rotta's debts, and that Janu must now set him free. Realizing that his plan for a final Dejarik match has been thwarted, Janu responds that Rotta is free "to die" and floods the arena with monsters, which prompts Mando and Rotta to work together to defeat them. Rotta breaks the arena's security systems, which sets the surviving monsters free, before escaping. Aided by Zeb Orrelios, Mando and Grogu pursue and capture Rotta.

Rotta claims that the Twins only want him so they can kill him and take over the Hutt Cartel. When Mando explains that he needs to give Rotta to the Twins in exchange for Coin's whereabouts, Rotta tells him that Janu and Coin are the same person. Trusting Rotta, Mando and Zeb raid Janu's compound and bring him back to Ward, who takes him in for questioning but warns that the Twins will not take kindly to Mando breaking his promise to deliver Rotta to them. Mando returns to Nevarro with Grogu. He enlists four Anzellans to modify the Razor Crest and helps Rotta go into hiding with a gunrunner. At night, Mando is captured by bounty hunter Embo, who delivers him to the Twins on Nal Hutta; Grogu and the Anzellans follow.

Mando is brought before the Twins, who have intercepted Rotta and are intending to slowly torture him for hundreds of years. To punish Mando for breaking his contract, the Twins remove his helmet and drop him into a pool of water which houses Amanin and the giant Dragonsnake; defeating the Amanin, Mando recovers his helmet and escapes with the help of Grogu and the Anzellans, but is mortally envenomated by the Dragonsnake in the process. Unable to fit aboard the small Anzellan ship, Mando stays behind on Nal Hutta, holding off his pursuers to cover Grogu and the Anzellans' escape as he succumbs to the venom. Grogu also chooses to stay behind, tending to the dying Mando and eventually saving his life using an antidote made by a friendly fisherman. The next day, Mando, now fully recovered, decides to go after the Twins instead of fleeing Nal Hutta, reasoning that they would still pursue him and Grogu.

Mando and Grogu break into the Twins' palace and battle their way through their droid security force before being intercepted by Embo. Mando duels Embo while Grogu frees Rotta, who fights the Twins; the fight eventually drops himself, the Twins, and Embo into the Dragonsnake pit. Grogu saves Rotta with the Force while Embo escapes through the tunnel Mando created earlier, leaving the Twins to be eaten alive by the Dragonsnake. The Anzellans return, bringing Ward and a New Republic squadron with them, to destroy the Twins' palace and droids.

Ward confirms Mando's suspicions that Janu and the Twins were working together, and Rotta chooses to stay and work with the New Republic. Mando and Grogu leave in the Razor Crest, on which Mando teaches Grogu how to fly.
