Waste Allocation Load Lifter Earth-Class ( Wall - E) has been doing just that for the last seven hundred years.Left behind on a desolate earth by humans who were forced out of this planet for their own safety, Wall - E has been collecting all sorts of knick-knacks.The human race decides to send out a search robot named Eve to check their chances of returning to earth.

Now even a robot who has been denied any kind of contact with anyone else, human or robot, for 700 years is bound to go zippity zee when he sees another robot.Eve realises taht Wall - E has found the path to the planet's future and she returns back to the humans to let them know the good news.Not wanting to let her slip out of his hands,Wall - E follows her to the ends of the galaxy if need be, setting off an exciting comedy adventure

WALL-E falls in love with the new robot on first sight, though EVE could hardly think the same of him. Eventually, EVE warms up to WALL-E and takes to his unique personality. When WALL-E shows her the plant he found, EVE's automatic programming initiates, causing her to seize the plant and store it inside her, activate a homing beacon for her ship, and shut down. WALL-E is unable to awaken EVE, but goes to great lengths to protect her from the elements, as well as take her motionless body out on a date. EVE's spaceship later returns to collect her; WALL-E, unwilling to leave EVE, hitches onto the ship's hull to follow EVE to her destination, the Axiom, the flagship of the human starliners. Aboard, EVE is taken to the bridge of the ship while WALL-E follows her; along the way he runs into several humans and robots, inadvertently giving them a refreshing new lease on life different from their dull routines.

On the bridge, EVE reactivates and prepares to present the plant to the ship's Captain so that he may place it in the ship's holo-detector, which will activate the ship's hyperjump and return to Earth so that humanity may recolonize the planet. However, the plant is discovered missing, and the Captain believes EVE to be malfunctioning. Both EVE and WALL-E are sent to the robot repair ward, but before EVE's diagnosis can be completed, WALL-E rescues her, mistakenly thinking that the repair ward robots are trying to harm EVE. In the process of freeing her, he accidentally releases all the other malfunctioning robots in the room as well, labeling both EVE and himself security targets. EVE tries to send WALL-E back to Earth via an escape pod to prevent him from causing trouble, but WALL-E simply refuses to leave without her. While the two argue, the Captain's robotic first mate enters the room with the missing plant which, as it turns out, he had stolen, and launches it into space in a pod set to self-destruct. WALL-E and EVE recover the plant before the pod explodes, and they celebrate with a dance around the ship before returning the plant back to the Captain.

EVE presents the plant to the Captain. Out of curiosity, the Captain reviews her camera logs and sees the devastated planet, belying the images of greenery he had seen from historical records; in the process, EVE views security footage showing WALL-E protecting her while she was shut down and realizes that she loves him. The Captain vows that humanity must return to make up for their mistakes but the ship's autopilot, aptly referred to as "Auto", reveals that Forthright had instilled a directive to prevent any attempt to return to Earth. Auto stages amutiny, locking the Captain in his chambers and sending both WALL-E and EVE down a garbage chute with the plant, significantly damaging WALL-E along the way. As the robots recover, they realize the only way to repair the failing WALL-E is to return to Earth to his stash of spare parts, and the fastest way to do so would be to insert the plant in the holo-detector. With the help of some of the malfunctioning robots from the repair ward and the Captain, WALL-E and EVE surmount the efforts of Auto and the security systems to prevent them from activating the holo-detector, though WALL-E suffers further damage to the extent that he is crushed. The Captain, standing on his own two feet for the first time, is able to deactivate Auto, allowing the humans and robots to help insert the plant into holo-detector, and the ship makes the hyperjump to Earth.

As soon as the Axiom lands on Earth, EVE attempts to repair WALL-E. Though she is able to restore his body, his memories and personality seem to have been erased, his waste-disposal programming taking over. EVE is heartbroken and mournfully gives WALL-E a farewell "kiss", actually a power spark, which reboots WALL-E's memory. The two robots embrace happily as the humans from the Axiom take their first steps on Earth, carefully replanting the seedling that brought them back, and begin working alongside the robots to restore their home.
