‘Star City’ Episode 4 Recap and Ending Explained: The Show’s Most Emotionally Complex Hour Yet, and Irina’s Choice Changes Everything

Apple TV’s Cold War thriller has been building toward a moment of reckoning, and “Dark Forest” delivers it with quiet, devastating precision. ‘Star City‘ follows an alternate-history version of the Soviet space program, and episode 4 continues the storyline as internal investigations and public attention on key figures intensify. At the midpoint of its debut season, the series has evolved from a slow-burn spy drama into something far more morally tangled.

What makes “Dark Forest” stand out from the rest of the season is how it refuses to let any character off easily. At the halfway point for the first season, things are really heating up, with the Venus mission rapidly progressing, more details emerging about how Valya was turned, and Irina putting the pieces of the puzzle together. Every storyline converges with the quiet efficiency of a show that knows exactly where it is going.

Valya’s Secret and the Cost of Protecting Love

The emotional spine of the episode is the full reveal of why Valya became an American asset, and it is far more human than expected. Tanya was once involved in dissident activities like smuggling records of artists banned by the Soviet Union.

The Americans kept an eye on her and discovered Tanya and Valya’s budding romance, and they recognized Valya as a potential asset before he was transferred to Star City, where surveillance opportunities would be limited.

By the time Valya was approached by an American agent, he was already married to Tanya. The agent possibly threatened to expose his wife’s dissident activities if he refused to cooperate, and that was how Valya became an American asset. It reframes everything the audience thought they understood about him and repositions his betrayal not as ideological defection, but as an act of desperate love.

This backstory transforms Valya into one of the season’s most tragic figures. A man who never questioned the system did not abandon it out of conviction but out of fear of losing the one person who made it bearable. The show trusts viewers to sit with that moral grey without offering easy resolution.

Lyudmilla Under Pressure From Moscow

Lyudmilla was under immense pressure to find the mole in Star City. From the lunar base model getting exposed before launch to the high frequency signal picked up during the Luna 17 mission, it was evident that someone inside Star City was working for the Americans. That pressure reaches a new level when Moscow calls.

Lyudmilla received a summons from Commander Director Konstantin, and in Moscow she was introduced to Comrade Petrovsky, the first deputy, who would be studying her reports on the security breach. The meeting carries an undercurrent of threat disguised as bureaucracy, which the show renders with unsettling naturalism.

The deaths of Yana Akhmatova and Arseni Vetrov weigh heavily on Lyudmilla’s position. Yana was not an American agent and was shot dead due to a KGB agent’s mistake, while Arseni died in space after Lyudmilla ordered the cosmonauts to reboot the entire system despite the Chief Designer’s warnings. Should any of that truth surface, her career would collapse. Irina is her only viable path forward.

Anastasia’s Fame and What the Soviet Machine Does With Heroes

The episode follows Anastasia as the consequences of her growing public fame begin affecting both her personal life and her role within the Soviet space program. This storyline offers the episode its most nuanced commentary, exploring how authoritarian systems consume and redirect individual achievement.

After becoming the first woman to land on the Moon, Anastasia’s routine involved regularly giving lectures at women-centric events and visiting schools and colleges to inspire young students.

She was heartbroken when she discovered that the state had decided she would not be allowed to go on any more space missions, because she had become too valuable as a symbol of progress that the Soviet Union could flaunt to the world.

During a school visit, Anastasia was candid about wanting to simply be a regular farm girl who milked cows and stared at the constellations. One teacher invited her to his farm, and there she had the time of her life, drinking beer, swimming in the lake, and setting off bottle rockets, a rare moment of ordinary joy. It is in that unguarded moment of freedom that her connection with Sasha deepens into something romantic.

Irina’s Discovery and the Ending That Leaves Everything Hanging

Irina met the head of the company that manufactured the transmitters found during the Luna 17 investigation. The man confirmed the metal coil was not Soviet, as it was an unusual alloy not manufactured in the USSR, and explained that the material could have been used as a heat sink, capable of handling a power supply several times higher than standard ones.

Irina concluded that the Americans had set up a trap to spy on the Soviets during the Luna 17 mission. She decided to go through purchasing records to determine if someone from Star City had bought a Soviet transmitter and later added the micro transmitter to it.

Her methodical approach has been one of the season’s quiet pleasures, and this episode rewards that patience with a breakthrough that the finale of the episode pulls like a pin from a grenade.

As the episode ends, Irina faces a tough choice. It is a discovery that will change things for her professionally, but it also puts her friendship on the line. The show does not let her linger. It simply cuts, leaving the audience to sit in the weight of what comes next.

The Chief Designer’s Venus Gamble Escalates

The Chief Designer brought a new scientist, Dr. Chadha, on board for the Venus mission. She initially believed she would be working on lunar missions, but soon learned about the secret Venus plan and that the Chief Designer wanted to incorporate her research on self-sustaining generation of breathable air into it. The mission keeps expanding in ambition while its secrecy becomes ever more precarious.

The Chief Designer approached Pavel and Sasha to become the first cosmonauts to travel to Venus. Pavel agreed immediately, while Sasha’s guilt over what happened during Luna 17 made him hesitant.

If Sasha goes, he will be away for nine months with no guarantee of return, and the mission is not sanctioned by the Soviet Union. It is the kind of impossible choice the show excels at constructing, where every option carries a cost too high to calculate.

After four episodes, ‘Star City’ has become one of the most impressive shows on television, and “Dark Forest” cements that reputation by refusing to simplify what it has built. The real tension now is not whether the Americans will be exposed, but whether the people who uncover the truth will survive doing so within a system that punishes honesty as readily as treason.

If you have already watched “Dark Forest,” share your thoughts on whether Irina will protect Valya or report him, because that decision is going to define what kind of show ‘Star City’ truly is.
