In 2805, Earth has been polluted with waste and humanity has abandoned the planet, by boarding a giant cruise ship called Axiom. They have built hundreds of domestic robots called WALL-E, who made a piled cubes of waste in an attempt to restore the planet for the company. Seven hundred years later, one robot spends most days, cleaning the city and collecting essential properties, before finding a surviving plant hidden in a refregitor.
A rocket appears and assigns EVE to investigate the city. WALL-E meets and invites EVE into his home. He shows the hello dolly movie on a recorder. When WALL-E shows a plant for EVE, she takes it and becomes deactivated. The same rocket appears on Earth, takes EVE and returns to outer space, with WALL-E following it.
As the rocket returns to the ship, WALL-E notices that all humans had gained weight and lost some bones, while sitting on each chairs, and every robots serve them. The AUTO and Captain McCrea examine EVE's body in the main dock, only to find the plant gone.
When WALL-E inadvertently destroys the security system at the repair ward, he and EVE escape from the hallway. EVE attempts to send WALL-E to the escape pod, but they discover that Gopher placed the plant in the pod, when he stole it from EVE. WALL-E uses a fire extinguisher to save himself and the plant, before the pod self destructs.
The robots return to the ship. As McCrea watches each videos EVE recorded on Earth, he decides to return to Earth. AUTO informs McCrea that they cannot return home, because the recorded video revealed that how humans survive in space forever. As Gopher discards the plant in a waste shaft, WALL-E hides it, before he and EVE are sent down to the shaft by Auto, and McCrea is trapped in the room.
EVE wakes up and saves WALL-E from being sent into space. They help all humans and robots take control of the ship. When Auto damages WALL-E's body with a machine, McCrea recovers and disabled Auto. After the ship returns to Earth, EVE repairs WALL-E's body. Though WALL-E cannot remember EVE, the spark makes them remember each other. The movie ends with all humans and robots restoring all life on Earth.
