While Shanice helps to prepare the Bois Blanc for a celebration, others are preparing for war. LaDonna returns to the hotel and we learn what she has experienced out in the real world and what she knows about the 44orum. After a disturbing incident, Hayden realizes the comfort of Kaminsky home may not be what is safest for everyone. Jharrell reunites with his brother but is Manny to be trusted and what is his connection to Claudette? Meanwhile, an unfortunate misunderstanding might prove fatal for one of the 4400.
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. As the government races to analyze the potential threat and contain the story, the 4400 themselves must grapple with the fact that they've been returned with a few... upgrades, and the increasing likelihood that they were all brought back now for a specific reason.
