In an initially bleak, but lateron downright apocalyptic future, mankind has become infertile making a cult of the young. This infertility is only one of the problems. There is massive inequality. In the UK the situation is the least bad of the globe and many go their to test their luck. These immigrants are aggressively kept apart from the original inhabitents who enjoy a relatively good life. Activists try to change the system and persuade the former activist (and now bureaucrat) Theo to assist in their cause.
The atmosphere of the film is descent and the story makes easy links to our own time thus making “Children Of Men” a film to think about.
