Annie Walker is removed from CIA training and thrust into the inner sanctum of the Agency for what appears to be their need of her exceptional linguistic skills, but there may be something or someone from her past that her CIA bosses are really after.

New CIA agent Annie Walker is still forced to work on low-key cases until she is tipped off that a IRA cell operates in America.

Annie is tasked with getting close to Diego, a college student, in the hopes that his sister, Julia, will provide the CIA with intel on Victor Ponces, a corrupt Venezuelan government official. But when the CIA station agent looking into Ponces goes missing, Diego's trust in Annie means that she's going to have to finish the job.

Annie needs Auggie's help to return from Zurich where she is stranded with an untrustworthy Mossad agent. At the agency, Joan and Arthur suspect Auggie to be the CIA's leak.

In order to stop a weapons shipment, Annie asks a former operative for help and attracts Henry Wilcox's and her former lover Ben Mercer's attention.

When the national security is threatened, Annie tries to find the leak in the Senate Intelligence Committee. Meanwhile, Auggie starts working as his old unit's handler.

Auggie is assigned to track a hacker responsible for shutting down communication systems throughout the city who also happens to be his ex-girlfriend.

Annie faces Ben again while she investigates a suspicious art-auction purchase.

An Iranian trade delegate who escaped his handlers approaches the CIA to cut a deal. In exchange for entry to the United States, he is willing to hand over stolen intelligence.

A new assignment Annie has to convince smugglers to hire her. Meanwhile, Henry Wilcox is invited back by Arthur and Joan.

Ben Mercer walks into the CIA Headquarters and confronts Annie with her past.
