C-3PO and R2-D2 are sent to Jabba's palace on Tatooine in a trade bargain made by Luke Skywalker to rescue Han Solo from crime lord Jabba the Hutt. Disguised as a bounty hunter, Princess Leia infiltrates the palace under the pretense of collecting the bounty on Chewbacca and unfreezes Han but is caught and enslaved. Luke soon arrives to bargain for his friends' release, but Jabba drops him through a trapdoor to be executed by a rancor. After Luke kills the rancor, Jabba sentences him, Han, and Chewbacca to death by being fed to the Sarlacc, a huge, carnivorous plant-like desert beast. Having hidden his new lightsaber inside R2-D2, Luke frees himself and battles Jabba's guards while Leia uses her chains to strangle Jabba to death.
