Based on Robert J. Sawyer's sci-fi novel Flash, the project chronicles the turmoil that occurs after everyone on the planet passes out for two minutes and 17 seconds and has visions of the future. The central character, Mark Banford (Joseph Fiennes), is a newly sober FBI agent struggling to patch up his life and marriage.
Walger joins the cast as Mark's wife, Olivia, who is left unsettled by her vision of falling for a new man.
Also now on board is Christine Woods (Welcome to the Captain) as Janis, a techie FBI agent who helps uncover the crucial clue in the mystery. Courtney B. Vance and Jack Davenport were among the first to be cast on the pilot.
Woods credits include in the pilots Roman's Empire and the untitled Mike Birbiglia project this year.
