At last, the fourth installment of the zombiemeister's apocalyptic vision has the world under seige by the living dead and the last few human beings have holed themselves up within the walls of an unnamed city. But, being human, things go pear-shaped as internecine squabbling and conniving threaten to destroy the fragile peace, and when the undead menace start to use their "...braaains!" the gore really hits the fan. Action-packed and fun but without any of the smarts and character depth of the first three movies.
