Based on the futuristic MTV animated series created by Peter Chung, "Aeon" is set 400 years in the future, when disease has wiped out the majority of the earth's population except for one walled, protected city- state, Bregna, ruled by a congress of scientists.
Theron plays the title role, the top operative in the underground "Monican" rebellion, led by the Handler, played by McDormand. When Aeon is sent on a mission to kill the government's leader (Marton Csokas), she uncovers a world of secrets, which makes her question everything she thought she knew.
Karyn Kusama is directing the project.
