Over the last century at least four thousand four hundred people who were overlooked, undervalued, or otherwise marginalized vanished without a trace off the face of the planet. Last night, inexplicably, they were all returned in an instant to Detroit having not aged a day and with no memory of what happened to them.

4400 overlooked, undervalued, or otherwise marginalized people who vanished without a trace over the last hundred years are all returned in an instant, having not aged a day and with no memory of what happened to them.
