For All Mankind S4E9 Review: The Heist Crew Closes Ranks Before Ranger's Burn
Penultimate hour pulls the hijacking conspiracy into daylight, drags Ed into honesty with his daughter, and leaves Miles in cuffs as the clock on Goldilocks runs down.
For All Mankind has spent S4 building two competing engineering projects on the same base. One is the M-7 plan to ship Goldilocks home and pour every dollar into Earth orbit. The other is a counter-hijack run out of Dev Ayesa’s locker, a North Korean module, and a smuggler’s storage cage, designed to keep the asteroid at Mars and the Mars program funded. “Brazil” is the episode where those projects collide. By the time Miles Dale is face-down on a Happy Valley deck and Margo is being asked to flee to São Paulo with Sergei, the show has stopped letting any of these people pretend they are still the ones in control of what they started.
The hijack rig finally answers Ranger
The cold open is a procedural triumph staged as comedy. Dev and the smuggling crew have been pinging Ranger for nineteen attempts and counting, and every attempt has bounced off Ranger’s discriminator. Sam Massey has been onboard a month and has not yet swapped the unit. Goldilocks burns for Earth in forty-eight hours. The math is brutally simple, and the show lets the team voice it without flinching: if Sam does not finish the swap, the rebellion never gets to make its case.
The episode then lets the swap happen. A burned-out video tap on a NASA surveillance line in the North Korean module gets logged out, Samantha Massey installs the spare on Ranger, and the next ping authenticates. The room exhales. Dev’s line, “Our discriminator’s in and we control their engines,” is the closest the season has come to a heist-movie beat, and the show plays it straight rather than triumphant. Owning Ranger’s engines is not victory. It is permission to attempt the next, harder thing. The discriminator that bounced the test pings is the same component that will, in the finale, decide whether Goldilocks turns left at the burn.
The contrast with Danielle Poole’s simulated burn-termination drill on the other side of the wall is the episode’s quietest joke. Danielle runs her crew through reactor standby, argon-tank pressure sims, anchor-stress green-board confirmations, all of it nominal, all of it neatly done. She tells Ranger she will not get a second bite at this apple. She is right about that and wrong about whose apple it is.
Lee Jung-Gil chooses the conspiracy
Lee Jung-Gil’s recruitment is the structural keystone of the hour, and the show treats it with the seriousness it deserves. Dev needs the North Korean module’s video feeds to watch the rest of Happy Valley while the heist crew works. Lee, alone in a glass capsule for seven months once and now a defector whose wife Moon Yeong is still in Pyongyang, calls the ask dangerous. Dev counters that staying in that capsule was not a choice; this is. The negotiation is brief because Dev has the only leverage that matters. Helios transports are the way Moon Yeong gets out. The asteroid is the way Helios survives long enough to fly them.
Lee says yes. Within minutes the room has video and audio from PRK Ops-Com, and Ed cracks the only honest American joke of the episode: God bless North Korea. The visual irony of Cold War 2.0 watching Cold War 1.0’s panopticon to run a sabotage op against the M-7 is left for the audience to register, but the show frames it cleanly. The Brazilian space program subplot Sergei pitches Margo later in the hour rhymes with this: the people who built the old order are starting to negotiate with whoever will host them next.
The North Korean storyline also delivers the episode’s most pointed comic-political beat. Commander Cho discovers the video tap during a screen-static gripe, and the diplomatic confrontation that follows reads like a stage play. Cho demands punishment, demands an investigation, demands that no American foot cross the threshold of “sovereign soil.” Eli Hobson, exhausted, asks if it can wait until after the asteroid mission. Then Cho’s translator delivers the line that detonates the rest of the episode: Helios technician Miles Dale is the only one who has been in our module. Arrest him. The smuggler whose black-market hustle the season has used as comic relief is suddenly the named suspect in an interplanetary espionage incident, and Eli Hobson has to take the lead seriously.
Ed and Kelly do the conversation the show has been postponing
The Ed-Kelly material is the heart of the hour and the season’s first sustained honesty between them. Joel Kinnaman plays Ed in two registers across the episode. With Alex he is a grandfather promising Star Trek marathons, Bob Newhart, MAS*H, Columbo. He cries the moment he realizes he will get to watch the boy take his first steps, calls Alex his proudest achievement, says he intends to be the best goddamn grandma on the planet. The line lands because Ed Baldwin saying he wants to be a grandma is the gentlest line the character has had in four seasons.
Then Kelly walks in on him while the base is being torn apart by search teams, and the second register arrives. She knows. She has known for a while. She points out that he used to think Dev Ayesa was the devil incarnate and now they whisper in corners. She tells him to stop lying to her. The confession Ed gives in response is the episode’s strongest piece of writing. He talks about Gordo’s father dying of cancer, terrified at the end, weak. He says he never wanted to come home because he does not want to end up in a nursing home with a diaper and a drool cup, squeezing a ball of wax in front of the TV, not remembering who he is. He says Mars is the only place where he is building something. Possibly even a place his grandson’s children could live. The Mars-as-legacy argument Dev has been making in boardroom register all season, Ed makes in his living-room voice, and it is the version that works.
Kelly’s reply, that she does not think he is crazy, maybe a little, is the closest the show comes to a punchline this year. Ed apologizes for not being there for her and Alex, for ever lying to her. Cynthy Wu plays Kelly’s grief and relief without overdoing either. Then Kelly asks the question the audience has waited an hour for: so you are going to tell me what you and Dev are up to. The cut is the episode’s smartest editing choice. The show does not need to dramatize the briefing. It needs Kelly to be inside the tent before the finale starts.

Margo, Sergei, and the Brazil escape hatch
The Margo-Sergei strand operates at a different temperature than the rest of the episode, and the show lets it. Wrenn Schmidt plays Margo as a woman who has agreed to one more mission and is being asked, urgently, to plan the day after. The dinner at Aleida’s house in Houston is staged with deliberate domestic warmth: Victor cooks, the kids hover, Coral Peña’s Aleida runs interference between her family and her old mentor and the Soviet defector she has agreed to harbor. The trajectory math gets done. The Apollo-Soyuz joke gets made. Sergei calls it Soyuz-Apollo “for the sake of convenience.”
What the strand actually argues is harsher than the warmth suggests. Sergei tells Margo the truth Korzhenko has not bothered to hide: the M-7 will withdraw from Mars the moment Goldilocks reaches Earth, NASA will follow, and the next Mars program will be a memory the way the 1980s version was. He pitches Brazil. A friend high up in their space program. Protection in exchange for service. Building Brazil into a major space power the way they once tried to build the Soviet one. Margo agrees to think about it. The audience already knows she will not be allowed to.
Aleida’s silent read of the gift Sergei brings Margo, a record she has not listened to in too long, is the kind of small moment the show has earned over four seasons. The shot does not editorialize. It registers. Aleida understands what Margo and Sergei were and what they still are. The show keeps the verdict on whether to root for the escape ambiguous, because the season has spent itself earning ambiguity on Margo.
What this episode argues
“Brazil” is structurally a heist-movie penultimate, the one where the crew finally lines up their tools and the law finally finds its first credible name to put on a warrant. The argument underneath is about who gets to plan the next decade of Mars. Eli’s boardroom answers M-7 questions about iridium delivery timelines and admits there is no faster ship. Dev’s crew answers the same question by changing what the asteroid is doing entirely. Margo and Sergei answer it by trying to outrun both of them to a third country. Ed answers it by telling his daughter the truth so she can decide what to do with it. Each of these is a different theory of how a person, an agency, or a planet plans for an outcome it did not choose. The show is not picking between them yet. It is laying them on the same table so the finale can.
The other argument is quieter. The hour spends real time on Lee Jung-Gil missing his wife, on Ed crying about a grandson, on Sergei begging Margo to leave with him. The conspiracy at the center of the season is being run by people whose private lives are the actual stakes. The asteroid is the iridium that makes Mars matter to Earth. The people are the reason Mars matters to itself.
Verdict
“Brazil” is the strongest hour of S4 since the cold-launch episode. It pays off four episodes of slow conspiratorial scaffolding with a working hijack rig, a recruited North Korean defector, and an arrested smuggler. It pays off four seasons of father-daughter distance with one of the cleanest emotional scenes Ed Baldwin has ever been given. And it lands a closing beat, Miles Dale face-down with his arms about to break, that is exactly the cliffhanger a penultimate needs: not a twist, not a fake-out, just a named suspect in the wrong cell with twenty-four hours on the clock.
The episode’s weaknesses are the same ones the season has carried: the M-7 boardroom material remains the show’s least textured register, and the Brazil escape pitch arrives slightly too neat. But the procedural confidence is back. Danielle’s drill rhymes with Dev’s discriminator. Cho’s tantrum rhymes with Polivanov’s hospitality. Margo’s record rhymes with Ed’s MAS*H reruns. The series is operating on every level at once again, and “Brazil” earns its place as the bridge into a finale that will have to decide whether Goldilocks turns left.
Rating: 8.7/10
