After the events of Star Wars: Episode IX – The Rise of Skywalker (2019), Poe Dameron and BB-8 must make an emergency landing on the volcanic planet Mustafar where they meet the greedy and conniving Graballa the Hutt. The crime boss has purchased Darth Vader's castle and is renovating it into the galaxy's first all-inclusive Sith-inspired luxury hotel. While waiting for his X-Wing to be repaired, Poe, BB-8, Graballa, and Dean (a plucky and courageous young boy who works as Graballa's mechanic) venture deep into the mysterious castle with Vader's loyal servant, Vaneé.
