Meanwhile , at the Great Temple on Yavin 4 , the Rebels are celebrating the destruction of the Death Star , until C - 3PO interrupts them with the news that R2 - D2 has discovered something interesting . According to the Death Star plans , the battle station was carrying copious amounts of bacta as cargo . While Luke Skywalker , Han Solo and Leia Organa ponder what this could mean , Threepio receives a relay signal from a beacon in the system , and informs the Rebels that an unknown ship has entered the system . Their sensors indicate that it is a modified Carrack cruiser , probably searching for the Death Star . General Jan Dodonna orders that they lay low , and allow the ship to pass , but Solo disobeys , and sets out after the craft in the " Millennium Falcon " . Upon reaching the craft , Solo opens fire , and forces the Carrack to crash land on Yavin 4 . Dodonna decides that they must send a force out to stop the survivors from sending a distress signal and alerting the Empire to their presence . Dodonna selects one of the Rebels to scout ahead and survey the Imperial strength . The scout , using a speeder bike , reaches a clearing , and is nearly captured by Imperial stormtroopers , but quickly defeats them . The scout then finds more stormtroopers who are planning to launch a distress beacon , and quickly kills them too . Realizing that they will not be able to neutralize all of the Imperials , the scout disguises themselves as a Stormtrooper , hijacks an Imperial landspeeder , attaches their speeder bike to the back of it and sneaks into the Imperial camp . However , the scout forgets to turn off their comlink , and their cover is soon blown . The scout quickly escapes into a nearby temple to avoid capture . Within the temple , the scout encounters a battle droid , but defeats it . Venturing further into the temple , the scout encounters two more battle droids , and defeats them , as well as a worm - like creature . The scout then discovers Q - 7N , a security droid left by the Sith builders of the temple . 7N , thinking that the scout is an Imperial , sends the scout hurtling through a trapdoor , and pits them against two stormtroopers . The scout kills the two stormtroopers with ease , only for Q - 7N to reveal that they were in fact holograms . Convinced that the scout is friendly , Q - 7N aids them in their quest to capture the Imperial captain . The scout is able to escape , but is pursued by Captain Skeezer . Q - 7N slams himself against the captain , knocking him out and saving the scout . The scout then returns to the Rebel base with the damaged ancient droid . Afterwards , Artoo repairs Q - 7N , while Solo learns from the captured Captain Skeezer that the bacta carried by the Death Star was contaminated . Mission Pack # 1 .
