Far in the future, humanity live in peace with the robots. But as the planet dies and the resources get short in supply, the tension between these two civilizations are mounting. Humanity formed a totalitarian government where robots are confined into districts.
A small group of robots manages to escape one of these ghettos. They formed the Colony of robots (the good guys) that is a collection of resistance movements that fight against the new government.
