The year is 2700 and the Earth is polluted, barren and exhausted. Wall-E is the last of a group of clean-up robots, sent to restore the Earth by lifting and compressing the endless quantities of rubbish left behind by a human race that has withdrawn to the safety of space.
Wall-E spends every day doing what he was made for on the lonely, silent Earth. His only companion is his trusty pet cockroach, Spot. But soon, he will discover what he was meant for as he chases his dream across the galaxy.
