All the Devils are Here

Armand is brought to his knees in front of Daniel. They search him for a gun, and when Claude seems surprised that Armand is unarmed, Armand realizes that Claude must have been the one to plant the gun in Armand’s apartment. Thierry Girard, Claude’s former second-in-command at the Prefecture now in charge of SecurForte, mocks Armand’s situation. He commands Daniel to tell his father what he found out at the bank. Daniel tells Armand that Stephen had recently put an order to buy the stocks of two of GHS’s important smaller companies, one of which dealt with ore. Armand connects the dots between ore and neodymium, then remembers that Daniel still has the coins they thought were glued together in his coat pocket. Dussault gives Armand nine hours to find the documents Stephen has been hiding, and the threat is clearly against Daniel’s life. Armand points out that he’ll need help looking for a thing he knows nothing about. They agree to let him get Jean-Guy’s help, but when Armand calls him Jean-Guy excitedly tells him he and Annie are on the way to hospital because Annie is in labor.

Armand’s mind races as he tries to figure out what to do next. He finds himself tracing his steps back to where he had met Claude earlier that day, near the Fontaine des Mers. As Armand wonders why Claude brought him to the sight of the former guillotine, he has a revelation. He hails a taxi to the Hotel Lutetia, where he bribes the concierge to tell him where Alain Pinot is. The concierge sends him to the elite and private club Cercle de l’Union Interalliée, where Stephen’s JSPS card grants Armand entrance. Alain, seated with other members of the GHS board, spots Armand, and approaches him. Armand shows him his JSPS card, and the hostess shows them into a private room.

Alain and Stephen had indeed known each other well, and Alain had heard a lot about Armand from Stephen. Armand tells him about Stephen’s condition and the murder of Alex Plessner. Shocked, Alain confirms that Stephen offered to buy Alain out of his board membership for GHS. Alain tells Armand that he got his own seat on the board when his reporter disappeared in Patagonia, as an act of good will. Alain agrees to help Armand. They take a taxi to Place de la Concorde, where Armand fishes out a coin Claude had tossed in the fountain when the two men had met there earlier that day. Sure enough, the coin was actually the two Canadian coins stuck together, the same that used to be in Daniel’s jacket.

Annie is in labor while Jean-Guy and Reine-Marie wonder what Armand is up to. Armand takes Alain to the Archives through a roundabout way, trying to buy some time by throwing off his tail. At the Archives, Armand takes Séverine’s phone from her. Armand had figured out that she must be giving Claude information. Armand realizes that Claude must have confiscated the coins from Armand and thrown them in the fountain to retrieve them later. Understanding that Claude has a plan, Armand tries to think through what Claude could be up to. Armand takes Séverine outside to confront her about being an informant for Claude, but even though she is clearly afraid of Armand, she tells him nothing. Alain, Madame de la Granger, and Madame Lenoir are looking for relevant news from the dates Stephen highlighted on his business card. Suddenly, Armand has a revelation. The news from those dates features airplane and elevator accidents that killed many people. Armand realizes that it’s not the design of elevators and planes that killed people in these instances, but potentially the use of neodymium. Furthermore, the murdered AFP journalist had written an important piece on a train derailment in Colombia. Armand reasons that she must have figured out that GHS Engineering uses materials that are unsafe and risky, thereby indirectly killing people.

The severity of the situation begins to dawn on them all. At extreme temperatures, neodymium will implode. That’s why airplanes were going down. Now, GHS has built what they claim to be superior nuclear reactors, but if those are also made of neodymium, then that could mean several world-destroying nuclear explosions. Armand realizes that Alex must have figured this out as than engineer, then gone to Stephen for help in taking GHS down. It would have taken them years and millions of dollars to find irrefutable proof of their suspicions.

As Armand announces these realizations, Séverine runs off. Armand tells the others they need to find her because she works with Claude. Alain tells Armand that even if they do find Stephen and Alex’s proof, they can’t hand it over to Claude. Alain reminds Armand that if GHS knows that Armand knows all about their misuse of neodymium, they’ll all get killed no matter what. Armand figures that Stephen could have hid his proof right there in the Archives, knowing how good Reine-Marie is at research. He tries searching the research history with all of Stephen’s name associations, then remembers his conversation with Stephen at the Musée Rodin. Armand thought that when Stephen was making an elderly man’s mistake when he said that Armand had proposed to Reine-Marie in the jardin de Luxembourg. But Stephen had been giving him a clue in case he needed it. Armand types in “Joseph Migneret,” the actual location of his proposal.

The file Stephen had taken out and immediately returned is an old file on nails in Calais in 1527. While Armand has Madame de la Granger and Alain research places in Calais that might hold the real evidence, Armand finds Madame Lenoir in a back closet. She has found that document and lets Armand read it. It’s a thick file, and she knows it’s not just about nails in Calais. She helps Armand sneak out through a back entrance with the file, with just an hour to go to hand in evidence in exchange for Daniel.

Armand sees that SecurForte has surrounded him outside of the Archives basements. He quickly takes pictures of the proof in the file and sends them to Jean-Guy, Isabelle Lacoste, and himself. He sends a quick message to his family, reading that Annie has been moved to a C-section. Then, as he hears SecurForte coming in on him, he turns on the video of the factory battle with his officers. He puts the sound of his phone on the highest volume, then slides the phone away from him. He escapes to the sound of gunshots following him.

Loiselle finds his phone and watches the video again. Loiselle wonders who would help him in such a predicament.

Armand makes it back to Stephen’s apartment with seconds left. He hands the file of proof over to Claude and embraces Daniel. He is sure he and Daniel will be killed, but at least they will die together. Loiselle bursts into the room and hits Armand in the head with his gun, upset about Armand getting the best of him at the Archives. Loiselle confirms three bodies from the Archives, then Alain walks in the room. It was Alain Pinot who had betrayed Stephen. Only Alain had known where Stephen would be the night that he was hit by the truck, only Alain had known Stephen’s discovery of the truth about neodymium. Claude admits to moonlighting for SecurForte for the money, compromising his morals but reaping the financial rewards. Séverine’s job had been to keep the truth about neodymium a secret, and she was killed because she failed. Armand realizes that Girard and Dussault are planting clues to set up Carole Gossette. Carole believes she is working to help the police uncover the truth of a GHS mistake, but in fact the police are setting up a scapegoat should they need one.

Claude gets up to leave, and Armand tries one more thing to save his son’s life. He points out that there must be another piece of physical evidence, some sort of machinery that uses the neodymium. Otherwise, he reasons, how could Stephen have had the two nickels sealed by neodymium? Girard doesn’t know about the nickels, and Claude pretends he knows nothing about it. Armand reaches into his pocket for the nickels but sees a SecurForte officer try to stop him. Armand seizes the opportunity to take the officer off guard, grab him and shoot Claude with the officer’s gun. Daniel managers to escape the room and Armand falls back with the officer and loses his grip on the gun.

From his childhood days, Daniel remembers the hidden cabinet in Stephen’s armoire, so he goes to hide there. From the hiding spot, Daniel can see into the living room. Thierry Girard holds a gun to Armand’s head and calls out for Daniel to come out or he will kill his father. Daniel comes back out, and Girard shoots Armand repeatedly. Then, he searches Armand’s pockets for the nickels. Girard leaves Daniel and Armand with Loiselle while he brings Alain to the GHS board meeting with their newfound evidence. As they leave, they hear gunshots.

Meanwhile, at the hospital, Jean-Guy holds his new daughter.

The GHS Engineering board meeting commences. The others tease Alain for his disheveled appearance, and none of them seem to notice that Girard places a file in front of Madame Roquebrune, none seem to hear him tell her that the Prefect of Paris police had been killed in a terrorist attack the night before. The board meeting begins, and they quickly pass a motion. Then, the doors still open from the waiters bringing in fresh snacks and coffee, Daniel Gamache steps into the room. He tells Alain to get out of his seat, and Claude follows in right behind him.

At the hospital, Armand kisses Annie and meets his new granddaughter.

Before the meeting, back at Stephen’s apartment, Daniel had been surprised to find both his father and Claude alive. Claude instructs Loiselle to shoot the gun to throw off Girard. Armand reveals that he found cartridges filled with blood in the gun Claude had planted in his apartment. This clued Armand into Claude’s true role as ally, though he needed more time to truly understand it. He figured out that Claude had tossed the Canadian neodymium nickels in the fountain in front of Armand to communicate to Armand that he was trying to keep Daniel safe and that he wanted to keep that piece of proof safe from the SecurForte. Furthermore, Armand had hidden most of the real evidence from the file, but when Claude read the file and pretended it had all the secrets, Armand was more certain that Claude was on his side. Armand figured out that Loiselle was also on his side as he ran away from the Musée. He knew that Loiselle was shooting at him and purposefully missing because Loiselle is too highly trained to miss. Loiselle confirms that Séverine and the archivists are all safe. Claude reveals that a major step in the plan is unfurling at the GHS board meeting. He needs Madame Roquebrune to accept the file from Girard to prove that it is her, not Carole Gossette, who is responsible for GHS’s crimes.

Claude takes the board through the entire history of Alain and Madame Roquebrune’s involvement with the mine in Patagonia that secretly produce neodymium. Daniel tells the board how Alain sold his seat on the board to Stephen for hundreds of millions of dollars. With Stephen in critical condition, Daniel’s father has power of attorney and had put Daniel in Stephen’s place on the board. Claude arrests Alain and Madame Roquebrune.

The board of GHS Engineering agrees to shut down all nuclear power plants, ground all of their neodymium-made airplanes, and promote Carole Gossette to CEO to oversee the official destruction of the company. Meanwhile, Armand prepares to say goodbye to Stephen as he decides to take him off life support. Just as Armand is ready to bid his final farewell to Stephen, the doctor listens to Stephen’s heartbeat and straightens up.

The family, including Stephen, watch the children play in the jardin Joseph-Migneret. They are approached by a woman who introduces herself to Stephen as Arlette’s daughter. She shows Stephen a photograph of him with her mother. Stephen had helped save Arlette while in the Resistance. Back then, he had used the name “Armand” as a disguise.

The day Stephen survived being taken off life support, Armand and Reine-Marie went to his apartment where Fontaine and Claude were finishing up forensics. Armand wanted to show them the final proof of evidence Stephen had hidden. Behind the inconsequential, not at all famous watercolor painting, Stephen had a screw. The screw, when taken out of the wall, latched onto a lamp—samples of neodymium.

Daniel, Jean-Guy, and their families plan to move back to Montréal, as does a newly impoverished Stephen.

The Gamaches, Stephen, and the Beauvoirs return to a warm homecoming in their small village near Montréal.

Meanwhile, Claude Dussault is asked to retire as a roundabout way of accounting for the death of Alexander Plessner under his watch. He and his wife move to Sant-Paul-de-Vence. They receive a postcard from Loiselle, who has accepted a job in Nice and who wants to introduce them to his new girlfriend. They receive a piece of mail from the bank informing them that their mortgage has been paid off.

Back in Québec, Daniel finds the envelope his father had given him years ago, the one he had told he threw away. Inside was a note from Armand with a chain and crucifix, gifting Armand’s father’s chain to Daniel. Daniel shows Stephen, then helps him hang his watercolor painting up on the wall. Daniel notices that a note on the back of the painting is signed by none other than Arlette.
