Mission to Canto Bight The mission to Canto Bight , also referred to as the mission to Cantonica , was undertaken by the Resistance members Finn , Rose Tico , and BB - 8 during the First Order – Resistance war . Seeking to find the Master Codebreaker to help them infiltrate the " Supremacy " and save the Resistance fleet , the trio ended up being arrested , and in their escape teamed up with a codebreaker named DJ . Prelude . When the Resistance fleet tried to escape from the First Order , the First Order tracked them through hyperspace and remained in pursuit of them , led by Supreme Leader Snoke ' s Star Destroyer " Supremacy " . Led by Vice Admiral Amilyn Holdo , the Resistance fleet decided to flee instead of fight , to the displeasure of Captain Poe Dameron . Meanwhile , Finn attempted to desert the Resistance so that Rey did not return to danger , but he was caught and imprisoned by maintenance worker Rose Tico . However , while talking , Finn revealed that he could identify the tracking device on the " Supremacy " , and he and Tico got the idea to disable it . They shared this plan with Dameron , who agreed to it . However , the " Supremacy " was heavily guarded by a code that changed regularly , and so the trio contacted Maz Kanata to find a way to bypass it . Kanata was too busy to help them , but told them about a Master Codebreaker they could find on Canto Bight on the planet Cantonica . Kanata said they would recognize him by a red palm bloom on his lapel . Finn , Tico , and BB - 8 departed from the fleet on a Resistance transport pod to head for Canto Bight . The mission . Finn , Tico , and BB - 8 landed on a private beach in Canto Bight , and they entered Canto Casino to search for the Master Codebreaker . In the casino , Finn and Tico saw people racing on fathier s , and BB - 8 was mistaken for a slot machine by some customers , and became filled up with coins . They then found the Master Codebreaker , but before they could approach him , they were arrested by the Canto Bight Police Department for landing in an illegal area and were thrown into prison . In prison , Finn and Tico met a man named DJ , who claimed to be a codebreaker . The duo did not want to recruit him , and DJ managed to unlock all the prison cells . BB - 8 came to the prison , and bound and gagged the guards while they were playing cards . It then ran into DJ , and they were confronted by a policeman , but BB - 8 shot him with the coins that the casino goers put in it , causing DJ to take a liking to the droid . Finn and Tico escaped through the sewers , and ended up in the fathier stables . While facing the fathiers , they met some children who attended to the stables , and Tico showed one of them the Resistance symbol on her ring , earning their allegiance . They released the fathiers and rode them out , trampling over the police that came to stop them . Chased by more police , Finn and Tico rode the fathiers onto the racetrack before leading them into the casino , where chaos erupted as they trampled over everything and broke some of the gambling machines . After tearing apart the casino , the fathiers went back outside , but the police ships converged on them . Finn and Tico took them through a narrow alley that led them to the private beach , but before they could return to their transport pod , the police ships fired at it and blew it up . Having to keep going , the fathiers took Finn and Tico up a cliff into a field of tall grass . The tall grass caused the police to lose sight of them , but as Finn and Tico took the fathier they were riding away from the rest of the herd , they ran into the edge of the plateau , faced with a steep drop into the ocean . They released their fathier so it could graze in the wild with the others , but had nowhere to run . However , the Yacht " Libertine " came to them , piloted by DJ and BB - 8 after they had stolen it . Though Finn and Tico were reluctant to join DJ , they accepted his offer to help and escaped from the planet . While they were heading to the " Supremacy " , DJ confirmed he could slice through the shield and allow them to break into the Star Dreadnought . However , he wanted a precise estimation of his payment for doing this , even though Finn and Tico assured him the Resistance would pay as much as he wanted . DJ asked for Tico ' s Haysian ore medallion , and Tico agreed to give it to him , although Finn tried unsuccessfully to get it back as DJ looted the rest of the " Libertine " .
