Liaison (2023)

A cyberattack hits London's digitally controlled infrastructure, and British Home Minister Richard Banks assigns his trusted operative Alison Rowdy to identify who is behind it. At the same time, in Syria, French security chief Dumas sends Gabriel Delage to protect two Syrian hackers, Samir and Walid, who have stolen sensitive information from Assad's servers and may be connected to the attacks destabilizing England.

Gabriel's mission in Syria becomes more dangerous as the hackers and the intelligence they carry place him in the middle of a larger struggle between British and French security interests. The information the Syrians possess suggests that the London attacks are part of a wider operation, and Gabriel is pulled back toward Europe to continue the hunt while protecting the people who know too much.

Alison and Gabriel are forced back into each other's orbit in the course of the investigation, revealing that they were once lovers and that their breakup was caused by a betrayal Alison committed during an earlier period in their lives. Gabriel still carries the wound of that history, and the series repeatedly returns to the fact that Alison's choices ruined their relationship and altered the course of both their lives.

As the attacks continue, Alison and Mark travel to Brussels to negotiate a cybersecurity deal with the European Commission that could help Britain respond to the crisis. In parallel, Gabriel is sent into Belgium under a disguise to investigate Didier Taraud, a powerful French security figure, while also keeping watch over Myriam, Samir's wife, who is under threat.

Gabriel's employer pushes him to probe deeper into Didier's network, and Gabriel is instructed to extract information from Sabine Louseau, Didier's mistress and an EU employee. Gabriel meets Sabine, charms her, and gets her talking while Alison and Mark work on the Brussels negotiations. The political process and the espionage operation advance side by side, each one placing more pressure on the other.

Alison's personal life is also strained by the crisis. Her boyfriend Albert proposes marriage, adding another layer of instability to her already fractured emotional state. Around the same time, she is still trying to keep the Brussels deal alive while the cyberattacks continue and the political situation grows more volatile.

The pressure in Brussels peaks when Alison succeeds in persuading Vandermeer to sign the agreement that would let the UK rejoin the European Union's cybersecurity framework. Her success is immediately undercut when she discovers Mark hanging dead in the office, and it is clear that he has been murdered rather than having died by suicide.

Mark's death triggers a deeper rupture in the investigation. Alison reports what she found and identifies two strange men she saw in connection with the scene, but the French authorities show little interest in treating it as a murder case. Sabine, meanwhile, realizes that her role in Didier's scheme has gotten people killed, and the realization pushes her toward backing away from the operation and warning Alison.

Gabriel continues to maneuver around Sabine and Didier's world, including planting a bug in Sabine's computer when she is vulnerable. When Sabine learns of Mark's death, she becomes distraught and confides in Alison that he was murdered. In exchange for the information, Alison tells Sabine to be careful around Gabriel and reveals Gabriel's true identity to her.

The Samir thread tightens when Samir reaches out to Myriam, and the search for him intensifies. Gabriel, Myriam, and Alison eventually find Samir in France after tracing the contact, bringing the Syrian hack and the European attacks into the same physical space as the main investigators.

As the wider conspiracy advances, Didier and the Antropa network begin to use material from Alison's past against her. A video from her youth is uncovered and weaponized, showing Alison and Gabriel participating in a protest years earlier. The tape becomes a crucial piece of leverage because it connects their old relationship to the present conspiracy and exposes the origins of the fracture between them.

The flashback to the protest reveals what happened back then. During the demonstration, a girl is involved in an accident, which escalates the situation and threatens to expose the group. Alison's father tries to hand Samir over to the authorities in the aftermath, believing he is the real target, but Alison reveals that the person in their house is only a decoy. The actual Samir is hidden in a safe house with Myriam, while the bunker contains a fake version used to mislead their pursuers.

Attackers arrive at the house, and Alison's father insists on confronting them even after Gabriel and Alison urge him to get out of the way. He refuses to retreat, and the intruders kill him. Gabriel then forces Alison into the underground bunker with the decoy and locks her in, preserving the deception while the violence outside closes in.

Back in the present, another serious cyberattack nearly kills hundreds of people and puts Richard Banks under intense pressure from his superiors to take drastic action. The failure of the Brussels path makes a deal with the EU increasingly impossible, and the British side begins to treat Antropa as the only remaining option.

In the final stretch, Gabriel, Alison, Samir, Myriam, and their child are brought together again as the crisis reaches its peak. They arrive in London and take refuge in Alison's house while she waits for Richard to arrive, with the family hidden there as the political and security situation collapses around them.

In the end of Liaison, Alison discovers that Richard Banks was the hidden mole tied to the Antropa conspiracy, and that he had been using the crisis to cover his tracks. Gabriel survives the final ambush, Myriam is reunited with her child, and Alison walks away from Richard's side after refusing to join him.

Alison leaves the finale with the truth exposed around her and no real trust left in the people above her. Richard offers her a place in his arrangement, but she refuses, and that choice separates her from the conspiracy even though it leaves her inside the damaged political world around it.

Gabriel's ending is physically violent but survivable: he shields Alison during the gunfire, is left behind in the chaos, and later reappears alive after the attack. The finale does not clearly show the full extent of his injuries, but it confirms that he makes it through the ambush.

Myriam's ending is more direct and concrete: she is safe, and she is shown reunited with her son after the violence ends. The baby also survives and is out of danger by the last scenes.

Sabine is taken into custody by the authorities by the end of the story, while Didier, Bob, and Miller are caught up in the helicopter escape and then die when the helicopter explodes.

Here is the ending in a more extended, scene-by-scene narrative.

The final movement begins with the pressure still building around the testimony that could expose Antropa. Samir and Myriam remain the figures everyone is trying to protect, because their testimony and survival are tied to revealing who is behind the cyberattacks. Gabriel is still in motion, still trying to do the right thing after learning the mission around him was built on lies.

As the climax reaches its breaking point, gunfire breaks out and Gabriel throws himself into danger to keep Alison alive. He locks himself into a corridor and physically shoves her to safety, taking a bullet for her in the process. The scene carries the weight of their history together, but what happens on the surface is simple and immediate: he protects her, and she is forced to keep moving while the attack continues around them.

Alison escapes through a secret passageway and gets to a phone, where she tries to call for help as Didier, Bob, and Miller flee by helicopter. She reaches Richard instead, and he directs her toward an encrypted line by telling her to press the hash key on Ronald's phone. When she does, the helicopter explodes in midair. In that instant, Alison realizes the blast was not random; it was Richard destroying the evidence of his connection to Antropa.

After that realization, Alison tries to get away from the situation, shaken by what she has learned. One of Richard's men brings her back to Richard's car, and Richard finally speaks plainly about his betrayal. He says he joined with Antropa for what he saw as his country's sake, but that Antropa later shifted course, and he chose to eliminate them. He then asks Alison whether she will join him. She does not agree to him, and she leaves the car without saying yes.

From there, the final scenes show what remains after the violence. Alison sees Myriam reunited with her son. She also sees bodies being taken away by hospital staff, and she watches authorities escort Sabine away. These images make the cost of the conflict visible in plain terms: some people are saved, some are arrested, and others are dead.

At the very end, Gabriel appears in front of Alison. His return confirms that he survived the ambush, though the ending does not clearly state how badly wounded he is. Alison and Gabriel are left together in the aftermath, after everything that came between them during the operation, with the final beat giving them a brief moment after the chaos rather than a full resolution.

No. Liaison does not have a post-credit scene; the final moments of the season are scored over the closing credits instead.

The closest thing to an "extra" ending is the episode's final sequence, where the story resolves and then continues into the end credits with music, rather than cutting to a separate scene afterward.

Alison Rowdy and Gabriel Delage are former lovers whose past relationship becomes a central part of the story when they are forced to work together again amid the cyberattacks and intelligence crisis. Their history is repeatedly described as a long-ago romance that ended badly, and their reunion in the present creates both emotional tension and operational conflict.

Samir and Walid are Syrian hackers whose discovery of sensitive electronic evidence puts them at the center of the series. They uncover information tied to the attacks on London, and both British and French intelligence services treat them as crucial assets because what they know may reveal who is behind the cybercampaign.

The cyberattacks are the engine of the series' central investigation, pushing British officials to respond to a growing security crisis and driving the search for the people behind the assaults. The attacks include major incidents such as a train derailment and flooding, and they force Alison, Gabriel, and their respective agencies into overlapping missions.

Gabriel is sent to Syria by a French security figure to protect Samir and Walid after they steal highly sensitive information connected to Assad's digital systems and the wider cyberattacks. His mission is to secure the hackers and the information they uncovered, but the assignment pulls him back into Alison's orbit when the case widens.

Antropa is described as a hidden private organization that has infiltrated both governments and is working behind the scenes to advance its own interests. Its influence complicates the investigations, shapes the pressure on Alison and Gabriel, and helps explain why official channels are so compromised and unstable throughout the story.
