After the Millennium Falcon was captured by the Death Star, Luke Skywalker discovered that the Princess was scheduled to be executed. Skywalker embarked on a mission to save the Princess after enlisting the support of the smugglers Han Solo and Chewbacca. Relying on their recently acquried stormtrooper armor to disguise their identities, Skywalker and Solo "escorted" Chewbacca to detention block AA-23.
The ruse seemed to work until they arrived at the detention block. After the rescue backfired, it was Princess Leia who helped them escape the Death Star.... through a garbage chute.
“Somebody has to save our skins. Into the garbage, fly-boy!”
―Princess Leia, rescuing the rescuers by blasting a hole to garbage dump
