In the present day, 3 private agents are tracking a target in Antwerp, Belgium. They are supported by a local strike team Bundy and Manson, who covertly attack the target inside his home. But the target is prepared and launches a counterattack on the operatives. The target improvises normal house-hold appliances to convert them into weapons. This prompts the agents to come out and assist their strike team. When the team gets there, the target surrenders and the team have to fight off Belgian police to extract the target.5 weeks ago, CIA Agents Harris (Dermot Mulroney) and Bill (Jason Isaacs) are trying to get information out of Omar Abadi (Barkhad Abdi) at a black site. They are assisted by Visser (Annie Ilonzeh), and all three answer to Olsen (Mel Gibson), who is at the top of the command chain. Omar is held for receiving a large amount of money ($2 million) for his resistance group, the Crescent Democratic Front, which aims to oust the dictator, Bandar El-Mizdawi. But it seems that this amount of money came from a group that only associates with terrorists. The trio tries to get Omar to give in to the charges despite it being apparent that he has no prior information and is clean. Bill is sure that Olsen is holding something back on Omar. He asks Harris to take the call on this situation since Olsen is pushing them to kill Omar on very flimsy evidence. It is made clear that Bill and Visser have different motives and apply their own approaches to manipulating Omar. Visser brings in Omar's family to get him to confess, while Harris is the good cop. Bill believes that Omar is telling the truth. Harris, Bill's partner-cum-friend for years, observes on a screen from a nearby room. Harris tells Bill that El-Mizdawi is helping the CIA against Al-Qaeda, and a week after the deal was made, Harris and the team got orders to pick up Omar.Omar is ultimately killed by Visser under the excuse of defending herself from being shot. What follows is the revelation that Visser has her own orders from Olsen, and they include killing Bill too. And so, she shoots him as well in the interrogation room. This whole thing is observed by Harris, who makes a run with the footage of the whole incident and escapes before Visser and two guards (formerly thought to be working for Harris and Bill) can get hold of him.Back in the present, we see three private agents on their way to capture a person. This is also on order from Olsen. Later, we see Kavinsky (Adan Canto), Miller (Katie Cassidy), and Reese (Rhys Coiro) bringing the person in via air. Also, Kavinsky has been receiving encrypted messages since they were putting the person on the plane. Later, it is revealed that the person is none other than Harris. Kavinsky searches the entire plane before boarding it.Kavinsky is an ex-marine, and had been rejected by the CIA 5 times, and he had been taking on private assignments in the meantime. Olsen had called Kavinsky for a meeting a few days ago and asked him to undertake a mission as a test for his readiness to join the CIA. Olsen also met Miller, who had dropped out of college twice, and had beaten up her professor at Harvard Law School. Olsen recruits her for his mission. Someone from CIA (Called Control and later revealed to be Visser) is in contact with Kavinsky via messages and tells him not to talk to the target, or to open the encrypted messages that he has been receiving on his phone. In parallel, Control is in touch with Miller and tells her not let Kavinsky open the messages or talk to the target under any circumstances.Omar's interrogation, followed by Harris's capture, are both parts of Olsen's plan, which in turn is following orders from Langley (CIA headquarters). Omar is a sacrifice as a part of a deal struck between the CIA and El-Mizdawi (the very dictator that Omar and his organization intend to overthrow). El-Mizdawi would allow the CIA access to his resources to bring down Al-Qaeda (whom Mizdawi hates as well). In return, the CIA would have to stop those trying to overthrow him, e.g., Omar. Olsen is given the responsibility to handle the operation and, with loose ends never an option, he does all in his power to have a "clean-up," i.e., kill everyone associated with this operation without a trace.The team panics when Kavinsky finds body bags inside the plane, the cockpit door locks, and the plane starts descending. It is obvious that the team is heading into a trap. Needing answers Kavinsky wants to talk to the target. Miller stops Kavinsky but agrees with his logic and they decide to look at the messages he has been receiving from his unknown source. The message has a video showing Visser killing someone on her own team. All 3 team members say that Olsen told them that Visser would be running point on this Operation. Miller figures that the encrypted messages are coming from their target. The team agrees to now hear from their target, who is revealed to be Harris.Harris reveals that the team (bringing in Harris) would be intercepted by Visser after landing in Thailand, killed, and deemed KIA. But this doesn't happen as the team decides to work with Harris to foil Visser's plot. This video would prove Visser and her seniors guilty of killing a CIA operative. The senior in this case, is Olsen. Olsen, however, doesn't know anything about this footage.What follows is a gunfight between Visser and her men and Harris and the trio (Kavinsky, Miller, and Reese). Olsen had sent in a strike team to kill everyone, including Visser, but the team manages to fight them off. Visser realizes that she has been burned, when Olsen will not pick up her phone. In the ensuing firefight, Visser is killed by Harris. Despite Olsen's best efforts to kill everyone at the location, including a drone strike (to eliminate the strike team sent in to kill Visser and the team), Harris makes it out alive along with Kavinsky and Miller. Reese isn't able to make it. But to Olsen, everyone is dead, and the secret is buried underground forever.Two weeks later, Olsen receives a video feed that shows Visser killing Bill, proof that he can compromise him to the CIA big-time. Realizing that he is being tracked, he looks around and recognizes a white van. Despite being shot at, the van and its occupants (Harris, Kavinsky, and Miller) escape unhurt. Olsen contacts a man and telling him, "We have a problem."
