Dr. Schreber: I call them the Strangers. They abducted us and brought us here. This city, everyone in it... is their experiment. They mix and match our memories as they see fit, trying to divine what makes us unique. One day, a man might be an inspector. The next, someone entirely different. When they want to study a murderer, for instance, they simply imprint one of their citizens with a new personality. Arrange a family for him, friends, an entire history... even a lost wallet. Then they observe the results. Will a man, given the history of a killer, continue in that vein? Or are we, in fact, more than the sum of our memories?
