The Big O Season 1 The Call from the Past
Forty years ago, the minds of Paradigm City's inhabitants were wiped clean of all recollections of the past. Now, ruled by a powerful corporation and cut off from the rest of the world by desolate wastelands, Paradigm has become a virtual police state where Negotiators like Roger Smith keep the wheels of progress, commerce, and society turning.
