Approximately seven hundred years in the future, the Earth is overly-polluted with garbage and destructions of plant and animal life, because of years of careless use of environment. The surviving humans has abandoned earth and are living on the spaceship.

Humans created special robots to clean earth so they can comeback on earth later, but environment fails to recover and as time passes robots starts to destroy by harsh weather and non-friendly land, only one survives named WALL-E.

WALL-E spends his days converting garbage into solid blocks and building structures with them. He also collects some interesting stuff and keeps them in the garage which he shares with a cockroach, his only friend.

One day, a giant space-ship arrives and drops new robot named EVE.
Eve is sent on Earth to find is life exists on earth. EVE focuses on finding existence of life ignoring WALL-E completely as he was non living thing. Wall-E rescues EVE from a dust storm and provides her with shelter, where Wall-E shows her a last living plant.

EVE captures the plant and automatically enters into deactivated state. EVE becomes non-moving like statue. WALL-E, doesn’t understand what has happened to his new friend, but, true to his love, he protects her from wind, rain, and lightning, even as she is not responding.

Several days later a massive ship comes to take away EVE, as WALL-E didn’t wanted to lose EVE, he hangs outside of the ship. The ship arrives back at a large space station where all humans are staying.

WALL-E tracks EVE to the chambers of evil robots who were trying to destroy EVE as well the last living plant, as they wanted for humanity to perish.

The captain of ship finds out this trick of evil robots and with help of WALL-E and EVE, saves the last living plant and destroys all evil robots.
