Olivia receives disturbing news from Gabriel; Aaron's life is in danger as he continues to search for his daughter in Afghanistan.

Mark does everything in his power to protect Gabriel, who is the bridge between Dyson Frost and the Global Blackout. Aaron locates his daughter's captors and puts his life on the line in order to rescue her, while Simon comes face to face with the head of the nefarious organization that may be responsible for the blackout.

The day of the prophesized flashforwad date arrives as everyone waits to see if their predictions take place. Mark uncovers the date of the next blackout, and Simon, with Demetri, attempts to stop it from happening by breaking into the NLAP mainframe.
