Automata (2014)

2044. The climate change and a series of solar storms have turned in a desert the surface of the planet and annihilated to the 99.7 % of Earth's population, leaving alive 21 million people across the world in a single city covered by mechanical clouds (zeppelins anchored to the city) to make rain. Trying to rebuild the world again, a robot company named ROC Corporation create Automata Pilgrim 7000 with two security protocols: 1st, a robot cannot harm human beings, and 2nd, a robot cannot alter himself or another robot. But this situation changes when police officer Sean Wallace shoots and destroys a robot claiming that it was altering himself.
