The hit international spy drama returns this summer for its highly anticipated fourth season with Golden Globe®-nominee Piper Perabo as Annie Walker. This season kicks off after Annie and her longtime best friend and blind CIA tech-op, Auggie (Christopher Gorham) finally acknowledging their romantic feelings for one another. Things get complicated at the agency, as Annie aligns with Henry Wilcox (guest star Gregory Itzin) in a dangerous, undercover mission that has potentially scandalous consequences for the CIA. Joining the cast this season is Hill Harper ("CSI: NY") who will play Calder Michaels, an ambitious CIA station chief based in Latin America.
