As a result, reality begins to fracture, forcing him to attempt to fix something far beyond his control.
He is joined by Denise, played by Lauren Lapkus, along with a small group of familiar faces. The narrative also introduces alternate-universe versions of characters from the original series, opening the door for surprising returns and unexpected character dynamics.
