Plot

In Vienna, Veteran CIA agent Henry is reunited with his former colleague and lover Celia.

CIA agent Henry is tasked by his supervisor Vick to close an eight-year-old hijacking case that ended in tragedy. Vick has recently learned that there is a suspected mole who helped give the perpetrators information to impede the rescue attempt of the passengers. Being cleared by Vick, Henry is sent to interview his former colleague and lover Celia, a possible suspect due to her abrupt departure from the CIA the day after the hijacking. Celia, now married and retired, meets Henry in a California restaurant after he reaches out to her and asks her to dinner. Through multiple perspectives, timelines, and interviews, Henry, Vick, and Celia hope to find out what actually happened that day.—madnbryant

In early 2020, CIA agent Henry Pelham (Chris Pine) is informed by his boss, Vick Wallinger (Laurence Fishburne), that the CIA has reopened the case of Turkish Alliance 127, a 2012 terrorist hijacking which ended in tragedy. Headquarters suspects there was a leak from the Vienna station, where Henry and Vick work. One of the hijackers Ilyas Shushani, was recently arrested in Afghanistan and he divulged this information. Henry is sent to interview Celia Harrison (Thandiwe Newton), who also worked at the Vienna station at the time of the hijacking. Henry and Celia were lovers, but she left him shortly after the event.

It shown that first Henry meets another co-worker Bill in London and informs him of his mission to find the leak in the Vienna office in Flight 127 case. Unknown to Henry, later that night, Bill call Celia and informs her of Henry's mission.

Celia, now retired, lives in Carmel-by-the-Sea, California with her family. Henry meets her at an upscale restaurant, which is almost empty of customers and staff. As Henry and Celia talk, she reveals that an Austrian intelligence agent named Karl Stein (Corey Johnson) approached her shortly after she moved to Carmel. He wanted her to inform on her coworkers (Specifically Bill whom Karl says is selling state secrets to Islamist extremists), but she refused. Henry has Celia recall the events of the hijacking.

In a flashback to 2012, Flight 127 is on the runway when it is hijacked by four armed militants belonging to an Islamic terrorist group. The Vienna station (Including Vick, Bill, Collections agent Leila Maroof (Ahd Kamel), Ernst Pul (Jonjo O'Neill) (liaison with Austrian Intelligence), Owen Lassiter (David Dawson) (ran a team of code breakers and analysts. He shot himself a couple of months after 127). Henry himself was reassigned to Vienna from Moscow. Henry oversaw the Nord-Ost siege when Russian forces pumped gas into the building and killed all terrorists, including 100 hostages) jumps into action to address the crisis and learns that Ilyas Shushani (Orli Shuka), a Chechen and former informant for Henry, may be involved. CIA knew that Ilyas had arrived in Barcelona 2 days before from Tehran. They had intelligence that Tehran was going to fund a hijacking within the next 72 hrs.

The hijackers threaten to kill the passengers unless several of their comrades are released from custody (2 from Austria and 3 from Germany. They issue an ultimatum for 24 hours). Ilyas is not on the plane but is suspected to be coordinating this. Ahmed, a CIA courier who happened to be on the plane, contacts the CIA and suggests an attack via the plane's undercarriage. Celia uses her sources in Vienna and connects with a possible source named Mohammed (Nasser Memarzia), but the meeting seems to yield nothing of value, as Mohammed wanted money before he shared anything. Henry tells Celia and her mentor, Bill Compton (Jonathan Pryce), that when Henry worked in Moscow his superiors forced him to betray Ilyas to the Russian government to placate them after the Nord-Ost terrorist attack. So, the relationship between Ilyas and Henry didn't end well. Ilyas's family was killed, and he ended up in Tehran.

The Vienna station receives another message from Ahmed saying that the terrorists have a camera mounted on the plane's undercarriage and the assault should be called off. Bill leaves for home to deal with his wife. Celia goes into Bill's office after he leaves. Celia notices differences in the language of Ahmed's messages and fears he has been compromised. Checking the station's phone logs, she notices that a call to Iran was placed from Bill's office phone. Shortly thereafter the hijackers kill a passenger and throw his body from the plane, yelling "take away your spy".

Celia returns home and has passionate sex with Henry. When Henry was in the shower, she saw a call coming in on his mobile from a Tehran number. When the terrorists' demands are not met, they release Sarin gas, killing themselves, the crew, and all passengers. The Vienna station is devastated by the outcome. The next day, Celia breaks up with Henry and leaves Vienna.

In the present, Henry asks why she ended their relationship so abruptly. Celia reveals that she saw a call on Henry's cellphone from the same Iranian number that she found in the station phone logs. Realizing that Henry was the leak, she left him but did not divulge her discovery to the CIA. She further confesses that, after Henry contacted her to arrange this meeting, she contacted Karl Stein, and he arranged the meeting place, the staff, and fake customers, with the aim of poisoning Henry via his wine.

As Henry begins to succumb to the poison, Celia tearfully asks why he betrayed everyone to the terrorists. He explains that he was lured into a meeting with Ilyas, who had become radicalized and masterminded the hijacking. Ilyas' people staged the meeting between Mohammed and Celia to create the impression that Celia's life was in danger; this pushed Henry into revealing the presence of Ahmed on the plane, as well as the plan for an undercarriage assault in exchange for her life.

Celia reveals that Ilyas already gave Henry's name in Afghanistan. Celia just confirmed it. Henry comes to terms with his impending death, and Celia returns home to her husband and children. Karl calls Vick to report that Henry has died, revealing that they had been working together the entire time.
