Mad Max Beyond Thunderdome

The world is a post-apocalyptic wasteland caused by ecocide and a nuclear war over resources. In Mainland Australia, Max Rockatansky crosses the desert in a carriage pulled by a team of camels. The airborne bandit Jedediah and his young son attack him and steal his vehicle and animals. Max follows Jedediah's trail to a trading post called "Bartertown". Initially refused entry because he has nothing to trade, he impresses the local officials with his toughness, and the founder and ruler of the town, Aunty Entity, offers to resupply him if he completes a task.
Bartertown's energy comes from "Underworld," a subterranean refinery that turns pig feces into methane. The refinery is run by Master, a dwarf who rides around on Blaster, his giant bodyguard. "Master Blaster" has begun to challenge Aunty for control of Bartertown; Aunty wants Max to kill Blaster so she can subvert Master to her will.
Max infiltrates Underworld to size up Master Blaster and befriends Pig Killer, a convict sentenced to work there for slaughtering a pig to feed his children. When Master Blaster learns his newly-acquired vehicle belonged to Max, he forces Max to disarm its booby-trap. In doing so, Max sets off his alarm and discovers that Blaster is hypersensitive to high-pitched noises.
By law, conflicts in Bartertown are resolved by a fight to the death in Thunderdome, a gladiatorial arena. Max publicly accuses Master of stealing his vehicle, and a battle is scheduled against Blaster. Blaster dominates until Max blows a whistle, which makes Blaster grab his head in pain. Max knocks Blaster's helmet off and prepares to kill him, but relents upon seeing that Blaster has an intellectual disability. Max reveals Aunty's plot and Master threatens to shut down the refinery, so Aunty has Blaster killed. She is then able to terrorize Master into keeping the refinery running.
For breaking a deal, Max plays "Bust a Deal, Face the Wheel" where he lands on "Gulag". Max is bound, placed on a horse, and sent into the Wasteland. When the horse collapses from exhaustion, Max frees himself and continues on foot until he also collapses.
Warrior girl Savannah Nix finds Max near death and heals him. Her home "Planet Erf" is an oasis populated by a primitive tribe of teenagers and children known as the "Waiting Ones". The children are descended from survivors of a crashed Qantas Boeing 747, some of whom left to seek help and never returned. They believe Max is the pilot, "Captain Walker", come to fix the aeroplane and fly them to the fabled "Tomorrow-morrow Land". Max denies he is Walker and insists there is no longer any civilisation like that in their stories. Disillusioned, some teenagers and children led by Savannah want to attempt the journey to Bartertown, but Max stops them and has them tied up, saying everyone should go on living in the oasis.
During the night, the separatists escape. Max agrees to bring them back, taking some members of the tribe along. However, both parties are in bad shape by the time he catches up. Out of supplies, Max is forced to lead the contingent back to Bartertown.
The combined group sneaks into Underworld. With Pig Killer's help, the combined group frees Master and escapes in a modified truck along train tracks, destroying the refinery and most of Bartertown in the process. Aunty orders her forces to pursue and retrieve Master. Max and his group do their best to fight off the attackers. They come across Jedediah and his son, whom Max coerces into providing a ride in their aeroplane. With the approach of Aunty's army shortening the runway, Max gets in his vehicle which a child stole from their pursuers and crashes it into the oncoming attackers to create an opening so the plane can take off. Injured and alone, Max is spared by an impressed Aunty who leaves to rebuild Bartertown.
Jedediah flies Master, Pig Killer, and the separatists to the sand-covered ruins of Sydney. Years later, they have established a community with other wanderers. While they attempt to rediscover the knowledge of the pre-apocalyptic world, each night Savannah recites the story of their journey and they light up the city as a beacon for Max or any other travellers to follow. Meanwhile, Max wanders in the Wasteland alone.
