National security expert Elizabeth "Libby" Lamm (Sumpter) is hired as an adjunct professor of foreign policy at the prestigious Grant University. She is the former national security adviser to U.S. Vice President Rachel Burke (Curtis). She arrives amid protests and the university employees are cold to her, including her assistant and another professor who confronts her at a university mixer. Dr. Lamm is recognizable due to a Capital Dispatch op-ed where she explains and defends her role in an attack by US forces, revealed later in the film to be a strike on Homs.

Dr. Lamm is extra cautious about security, preferring to live her daily life without an email address, cell phone, landline or computer. Every night, she comes home to her study and writes feverishly on note pads at her desk. She has over a dozen of them completely filled and locks them in a vintage safe that she purchased from an antique shop. She walks around her home with a loaded Glock 17 and is always alerted to unfamiliar sounds. Dr. Lamm is being stalked by Martin Salhi (Ben Tavassoli), a graduate student at the university. Martin is withdrawn and sullen, and is intentionally standoffish from his roommate Jordan (Alex Weisman). Martin follows her home and later creates fake lawn service flyers as pretext to case her home. He breaks into her home and installs miniature cameras to observe her movements. He watches Dr. Lamm place the note pads in the safe.

One day, Dr. Lamm is approached at her home by Adrian (Jeff Hephner), the president's chief of staff. It is revealed that they were lovers when he was a policy adviser in the White House. He wants assurances that she will not reveal details of the Homs operation but she rebuffs him. A few days later, Adrian returns, this time demanding fidelity to the administration. Dr. Lamm angrily refuses. This incident prompts her to dismiss her class and rush home where she finds Martin breaking into her safe. While holding him at gunpoint, Martin admits to stalking and states that he was trying to understand how someone who could commit such an enormous atrocity, referring to the attack on Homs. He tells her that his parents and siblings lived in Homs and that he wanted "to understand the face of evil." Dr. Lamm then gives him the note pads she had been writing on to read. She is writing a memoir that she wants to be published that exposes the aggression behind the attack.

Four years earlier, Dr. Lamm is in the White House situation room and advises on a plan with a high-security group including the president and vice-president. She tells the group that 5 leaders of the most dangerous terrorist groups in the world, plus a nuclear scientist, will be meeting in Homs, Syria to discuss strategy. Dr. Lamm favors more conventional action but she is interrupted by Vice President Burke who overwhelming endorses Plan 712. The plan involves a nuclear strike that will result in an extreme mass casualty loss. Dr. Lamm ultimately and reluctantly endorses the plan. The attack kills the intended targets as well as causing the deaths of 150,000 civilians.

As Martin finishes reading, her home is broken into by undercover agents. Dr. Lamm and Martin escape and go on the run. Her intention is to take the memoir to her father Phillip Lamm (Clarke Peters), chief editor of the Springfield Register. They spend the night on the beach but Martin awakens to find Dr. Lamm gone, but the note pads were left with him. Dr. Lamm awakes in a basement and is approached by Adrian and current President Rachel Burke. President Burke tries to convince her to join her cabinet as Secretary of State in exchange for burying the memoir. Dr. Lamm realizes that the agents left the memoir with Martin and are surveilling him, hoping that he would lead them to more copies if there are any. She refuses President Burke's offer and is prepared to accept whatever consequences that come from its publication.

The president leaves and tells Adrian to release Dr. Lamm and end the surveillance on Martin. She believes she will be exonerated by the public by asserting the years of domestic safety as proof of its success. Adrian objects, believing that by not neutralizing the two, it will be political suicide. The president disagrees and overrules him. Dr. Lamm is released across the street from the Springfield Register. She enters the lobby and sees Martin and her father there. Suddenly a bomb explodes and destroys the lobby. It is revealed that Adrian acted on his own. Twenty-three people are confirmed dead including Dr. Lamm, her father and Martin, with the attack being blamed on him. After the apartment they shared was searched by the FBI, Jordan opens an email from Martin that was sent earlier. It contains copies of the memoir and asks him to give it to the media to reveal the truth.
