Plot Wall-E

In 2805, seven hundred years after mass consumerism facilitated by the megacorporation Buy-n-Large (BnL), Earth is an abandoned planet covered in trash. Giving up on restoring the ecosystem, BnL instead evacuates Earth's population in fully automated starliners, leaving behind an army of trash compactor robots called "WALL-E" to clean up. After five years, however, the planet was deemed too toxic to sustain life, forcing humanity to remain in space. In the beginning of the story only one WALL-E unit remains and has developed sentience. Along with his regular duties he also collects various knickknacks from the trash.

One day, WALL-E discovers a seedling growing among the trash and brings it home to his storage truck. Later, a spaceship lands and deploys EVE, an advanced robot sent from the BnL starliner Axiom with the directive to search for signs of life on Earth. WALL-E falls in love with the initially cold and hostile EVE, who gradually softens and befriends him. When WALL-E brings EVE to his truck to show her the plant, she automatically stores it, goes into standby mode and sends a retrieval signal. EVE's ship returns to collect her while WALL-E clings to its hull as it returns to the Axiom.

On the Axiom, the ship's human passengers have suffered from severe bone loss and become morbidly obese after 700 years of living in microgravity and relying on the ship's automated systems. The captain himself does little, leaving control of the Axiom to its robotic autopilot, Auto. WALL-E follows EVE to the bridge of the Axiom where the captain learns that by scanning EVE's plant sample with the ship's holo-detector as a sign of Earth being habitable again, the Axiom will make a hyperjump back to Earth so its passengers can recolonize. However, Auto has the plant stolen by the captain's robotic assistant GO-4 as part of a final directive to keep humanity away from Earth as life was incorrectly deemed unsustainable.

With the plant now missing, EVE is considered defective and taken to the repair ward along with WALL-E for cleanup. WALL-E mistakes EVE's inspection for torture and tries to save her, accidentally releasing a horde of malfunctioning robots, getting himself and EVE designated as rogue robots. Angry with WALL-E's disruptions, EVE brings him to the escape pod bay to send him home. There they witness GO-4 place the missing plant inside a pod, which is launched and set to self-destruct. WALL-E gets inside before it launches and escapes unharmed with the plant before the pod blows up. He then reconciles with EVE, celebrating with a dance outside the Axiom.

The plant is brought to the captain, who surveys EVE's recordings of Earth and realizes that they must return. However, Auto reveals his "no return" directive, stages a mutiny, and tasers WALL-E. EVE realizes the only parts for repairing WALL-E are in his truck on Earth, so she helps him get the plant into the holo-detector to activate the Axiom's hyperjump. The captain opens the holo-detector while fighting with Auto, who crushes WALL-E while closing the holo-detector. The captain deactivates Auto and EVE places the plant in the holo-detector, releasing WALL-E and sending the Axiom back to Earth.

EVE brings WALL-E's body back to his home where she successfully repairs and reactivates him. Unfortunately, WALL-E's memory is erased and he reverts to his original programming. Heartbroken, EVE gives WALL-E a farewell "kiss", causing an electric spark that restores WALL-E's memory and personality. WALL-E and EVE happily reunite and join the Axiom's humans and robots in restoring the Earth
