By the year 2049, Earth has been turned into a toxic waste dump. Humankind has fled into space leaving behind an army of mechanized “Orbots” to clean up the mess.

But when the Orbot leader “WarHead” goes haywire and starts a global revolt against the humans, it falls on the shoulders of the last Orbot loyal to its human masters to save the planet.

In 2049, the human population of Earth embarks on a migratory voyage to try to colonize other planets. They leave mechanical "orbots" to clean up the mess they made on Earth through littering and pollution.
