Ex-cop-turned-bodyguard Jericho Cane (Arnold Schwarzenegger) stumbles across a demonic state of affairs when he prevents the assassination of his Wall Street employer (Gabriel Byrne). It transpires that Cane's boss is none other than Satan himself, come to impregnate a young woman named Christine York (Robin Tunney) - who was secretly anointed by a satanic cult at birth - on the eve of the new millennium and so bring about the end of days foretold in the Book of Revelation. With the help of his partner, Chicago (Kevin Pollak), Cane now attempts to protect Christine from both Satan and a group of priests who believe that her death is the only way to halt Armageddon.
