The World
Set in the 29th century, WALL-E opens in a post-apocalyptic Earth, abandoned by humanity due to overwhelming pollution and waste. WALL-E, a waste-collecting robot, has been left behind to clean up, although it's an impossible task. Over centuries, WALL-E develops sentience and a personality, finding solace in the relics of human culture and an old tape of the musical "Hello, Dolly!".
Arrival of EVE
WALL-E's routine life changes with the arrival of EVE, a sleek, modern robot sent to Earth to find signs of life. WALL-E is instantly smitten and shows her a living plant he found. This discovery sets off a chain of events, leading them on a space journey to the Axiom, where the remnants of humanity live, oblivious to Earth's potential for recovery.
Journey
Aboard the Axiom, WALL-E and EVE battle to save the plant, which is the key to proving Earth's habitability. The film climaxes with their return to Earth, along with the humans who must learn to reconnect with their planet. The story concludes on a hopeful note, with humanity starting to rebuild Earth, inspired by WALL-E's dedication and love.
