" Low on fuel and power in deep space , the Ghost crew encounters massive , mysterious creatures whose lives are threatened by a mining operation . " Plot summary . Low on fuel and power , the crew of the " Ghost " are traveling towards an asteroid gas refinery to obtain fuel supplies for their ship and the Phoenix Cell . Hera Syndulla and Sabine Wren are piloting the " Ghost " towards their destination when Chopper enters the cockpit to deliver a status report . Suddenly , Ezra Bridger hears some high - pitched cries in the distance . Hera at first hears nothing but then Sabine spots several large creatures floating through space in the distance . These creatures turn out to be purrgil s , large space - dwelling creatures capable of hyperspace travel . As the purrgil herd swarms the " Ghost " , Hera wants to open fire on them but Kanan Jarrus urges caution . Ezra then counsels that Hera fly the " Ghost " in the same direction as the herd rather than against them . Ezra ' s idea works and the purrgils calm down . Through the Force , Ezra senses that the purrgils are trying to call out to them . Hera is dismissive , regarding the purrgils as " a big , lumbering menace " that block hyperspace travel . The purrgils begin to show signs of being startled . Shortly later , two yellow - streaked Mining Guild TIES appear and begin to strafe the purrgils . At the insistence of Kanan , the crew of the " Ghost " come to their aid . Kanan uses the " Ghost " top turret cannon to destroy the first TIE while Ezra uses the ship ' s rear cannon to destroy the second TIE . Sabine tracks down the TIE fighters to the asteroid gas refinery that they are traveling to . The crew of the " Ghost " quickly realize that the purrgil herd is also traveling to the same destination . Low on power , Hera orders her rebel crew to switch off all power appliances on the " Ghost " . During a private conversation , Hera confided in Ezra about her personal animosity towards the purrgils . When she was young , she had hear tales of how the space - faring purrgils had inspired people to develop hyperspace travel . However , Hera admitted that she did not believe in these legends and regarded the purrgils as a menace for crashing into starship s and endangering hyperspace travel . She had lost more than one friend that way . Ezra suggests that the purrgil are unaware of the harm they are causing . Shortly later , the " Ghost " computers pick up an energy source on an unidentified planetoid ahead which turns out to be the gas refinery . As they approach they gas refinery , Sabine studies the facility and devises a plan to infiltrate it . The " Ghost " lands on a nearby asteroid above the refinery . Zeb grumbles that the " Ghost " automatic doors are no longer working . With the crew assembled in the cockpit , Hera outlines their plan to steal fuel from the gas refinery . While Hera and Zeb man the ship ' s controls , Kanan , Sabine , Ezra , and Chopper will jump down onto an unguarded landing platform where several canisters of Clouzon - 36 lie awaiting pick - up by the Empire . To create a diversion and destroy the facility , Sabine plans to ignite the Clouzon - 36 . During the meeting , Ezra is too distracted by the purrgil to concentrate on the mission . Before they depart on the mission , Ezra confides that the purrgil also want the fuel but Hera tells him to focus on the mission . Meanwhile , the Mining Guild refinery ' s boss Yushyn complains about the purrgils to one of his Rodian subordinates . He orders the refinery ' s cannons to hold back the purrgils and to kill any that approach . When Yushyn asks about the two missing TIE fighters , the Rodian subordinate suggests that they may have encountered problems . Back on the " Ghost " , Kanan , Sabine and Ezra don helmets before their jump . Kanan is annoyed when he learns that Sabine has painted his stormtrooper helmet to make it more stylish . When Ezra asks how they are getting down , Sabine chides him for not paying attention . The rebels descend down to the gas refinery ' s landing platform with Sabine riding on Chopper . Kanan , Sabine , and Chopper land safely on a bridge but Ezra miscalculates his jump and plummets into the toxic atmosphere below . Kanan saves his apprentice by using the Force to levitate him . Shortly later , they are attacked by armed Mining Guild guards . Under Kanan ' s orders , Sabine activates the detonators but is restrained by Ezra . As they make their way through the facility , Ezra uses the Force to throw down a Rodian gunner . When confronted by his comrades , Ezra tells them that the purrgil are connected to the gas . Changing their plans , Kanan orders Ezra to man the gun emplacement while the other rebels secure the landing zone . Back on the " Ghost " , Zeb and Hera learn about Sabine ' s change in plans with Hera grumbling about the purrgils . With the rebels having breached the refinery , Yushyn orders the sentries to defend the Imperial shipment at all costs . Kanan , Sabine , and Chopper are pinned down by gunfire from the refinery ' s Rodian guards . Ezra comes to their rescue by firing the cannon at the sentries , knocking one out and forcing the others to retreat . With Sabine and her comrades having secured the landing zone , Hera lands the " Ghost " on the landing platform . Ezra is knocked off his gun emplacement by a Rodian gunner , causing him to plummet into the gas - covered crater on the planetoid below . Under enemy fire , the other rebels load the fuel canisters aboard the " Ghost " . Hera manages to use one of the " Ghost " turrets to knock out a gun emplacement and its Rodian gunner . Yushyn orders the refinery to deploy its TIE fighters , which begin strafing the " Ghost " . When Hera chides Sabine about the unsecured platform , Sabine replied that they had only temporarily secured it . Meanwhile , Zeb begins using a fuel canister to power up the " Ghost " systems . Under attack from TIE fighters , Kanan contacts Ezra to provide covering fire . Meanwhile , Ezra awakes on top of a purrgil known as the Purrgil King which comes to his aid by providing his helmet , thus saving him from death by asphyxiation . By staring into the Purrgil King ' s eye , Ezra is able to form a bond with creature and communicate with it . Together , Ezra travels with the purrgil herd towards the gas refinery . Meanwhile , the other crew of the " Ghost " are cornered by Yushyn ' s guards and TIE fighters . Yushyn issues an ultimatum demanding that the " thieves " surrender . However , Ezra returned with the purrgil herd and attacked the Mining Guild forces . While riding on a purrgil , Ezra used his lightsaber to slash off the wing radiator of a TIE fighter , causing it to explode in space . Meanwhile , Zeb completed powering up the " Ghost " and the ship was able to take - off with its crew . Yushyn attempted to leave to man a cannon but was cornered by two purrgils . One of them grabbed him with its jaws and dragged him down into the depths of the planetoid below . Before leaving , the " Ghost " bombarded the asteroid refinery in order to deny it to the Empire , causing it to explode . In space , Ezra is reunited with his fellow crew on the " Ghost " . Ezra tells his master Kanan that he had managed to establish a deep connection with the purrgils . As a result , he had learned that the crater was not their home but that they depended on the gas to survive and to travel into hyperspace . The gas refinery had been preventing the purrgils from feeding on the gas . Hera expresses gratitude towards the purrgils for helping them get off the ground . The rebels then watch as the purrgils jump into hyperspace . Having overcome her animosity towards the purrgils , she suggests that they follow them rather than return to the rebel fleet .
