Zardoz

The year is 2293. Society as we know it has broken down centuries ago with the Earth's population split into three classes: the Brutals, who work the land and are forbidden from reproducing; their overseers, the Executioners; and the highly civilised Eternals, who are protected from the outside world by a force-field. But when an Executioner, Zed (Sean Connery), smuggles himself into their isolated paradise, he risks unbalancing the system and threatening the status quo. (Arrow Films)
