Berlin Station

CIA officer Daniel Miller travels to Berlin for a covert mission to locate an anonymous whistleblower known as Thomas Shaw, while reconnecting with his former friend Hector DeJean. As Daniel closes in on Shaw, the target responds with increasing hostility and violence.

Daniel chases Shaw while Frost, Edwards, and Kirsch investigate a Georgian Islamic extremist to prevent a CIA operation. Hector's unexpected actions shake up the team by the end of the episode.

Frost and Kirsch become concerned that their hidden secrets may be exposed as Langley sends investigators to Berlin Station in search of information that could fuel future Shaw leaks. At the same time, Daniel's efforts to identify the mole face increasing danger.

Daniel and Hector pursue a high-risk mission to locate Shaw, while Valerie uncovers secrets about Iosava, and Frost and Kirsch discuss their next steps for themselves and the future of Berlin Station.

Daniel collaborates with BfV agent Esther Krug to stop a potential intelligence leak involving a foreign defector. Meanwhile, Valerie and Robert clash over how to proceed with her growing investigation into Iosava, and Hector receives an unexpected visit from Shirley Pimple in the middle of the night.

Valerie intensifies her investigation into Aleksandre and Ruth Iosava, leading to a joint German and American sting operation that involves Clare Itani, a CIA officer and Hector's lover. The unexpected involvement of Langley escalates the situation.

Frost deals with the fallout of the failed Iosava Operation as Robert investigates an alternative approach. Meanwhile, Hector acts independently, taking Daniel along and disrupting a key moment of insight.

Frost becomes isolated and the Station falls into chaos following the fallout from the Iosava incident, as Robert takes on a new position. Hector faces increasing pressure, Valerie discloses a personal secret, and Daniel makes progress toward uncovering the truth.

Daniel uncovers the truth behind Thomas Shaw's identity, forcing him to grapple with his own moral dilemmas. Meanwhile, Valerie grows more suspicious of Robert, straining their relationship, and Kelly Frost unexpectedly joins the team.

Daniel brings the team together to uncover Langley's role in the Iosava rendition. Steven and Kelly Frost reunite despite the challenges, while Hector explores a new path toward redemption. Meanwhile, the Thomas Shaw identity is transferred to a new individual.

Guided by the new Chief of Staff, BB Yates, Daniel Miller, Robert Kirsch, Valerie Edwards, and the team at Berlin Station launch a covert, unauthorized mission to investigate the threat of a potential Far Right terrorist attack.

Daniel enlists Hector's help to advance his mission involving Otto during a 24-hour episode set entirely in Spain, despite Hector's reluctance.

Valerie gathers intelligence on far-right activities, while Robert's son Noah arrives in Berlin and begins asking probing questions. At the same time, Frost accepts a request from the Ambassador to conduct surveillance at Berlin Station.

BB Yates confronts the implications of her past as she navigates the challenge of maintaining the secrecy of Berlin Station's Far Right operation or disclosing it to Ambassador Hanes. Meanwhile, Daniel uncovers growing tensions between Otto Ganz and his daughter, revealing a deepening lack of trust within the family.

A sting operation by The Station to entrap the Far Right in an arms deal fails, allowing Otto Ganz to escape. Robert and Frost shift their focus to tracing the financial underpinnings of the Party for Defense's activities.

Robert and Frost follow an illegal financial trail to Norway in connection with PfD, while BB and Valerie enlist a Far Right figure for a new strategy. Meanwhile, Daniel struggles with the psychological aftermath of his recent mission.

April considers whether to inform Robert about Hector's assassination plot, while Daniel works with Esther to secure Hector's escape from Berlin.

Hector faces charges from German authorities for the murder of Katerina Gerhardt, prompting Berlin Station to investigate and uncover a more complex situation than initially appears.

The team at Berlin Station investigates the circumstances surrounding Katerina Gerhardt's assassination and Nick Fischer's involvement, while tensions rise over a protest at the US Embassy and demands for Hector's surrender.

Daniel Miller and Robert Kirsch are dispatched on an urgent mission by Valerie Edwards, where they encounter rogue CIA officer Rafael Torres and begin to uncover evidence of a secret invasion.

Berlin Station continues the investigation into evidence obtained by Kirsch during his mission, helping to solidify the team's theory about a potential impending invasion.

Rafael Torres is tasked with finding the last known location of a missing comrade, Daniel Miller, which leads him into dangerous territory. Meanwhile, Kirsch pays a visit to an old friend.

A fishing boat explodes, drawing the attention of the Berlin Station. CIA agent Rafael Torres defies orders and recovers what he believes to be the body of the missing agent Daniel Miller from the wreckage.

Kirsch and Torres embark on a dangerous mission to locate a fallen colleague. Meanwhile, the return of B.B. Yates to Berlin forces the Station to evaluate the reliability of a high-ranking U.S. government representative.

Valerie and B.B. enlist the 14-Eyes intelligence alliance to aid their mission. Kirsch and April use Sofia to lure Sergei into a trap and propose a prisoner exchange for Daniel. Meanwhile, Esther deploys a German special operator to track Daniel, and Frost works to infiltrate Russian elites through a new contact while gathering compromising information on a former Krik associate.

Valerie is shocked when B.B. sides against her in a critical vote regarding the 14-Eyes and Article 5. April struggles as her technology is seized and she faces deportation. Meanwhile, Kirsch's espionage operation goes wrong when the wrong agent is exchanged, and Hector and Torres are drawn into a dangerous encounter with Russian oligarch Krik, where Hector becomes a target in a deadly game along with Daniel.

Daniel and Hector take refuge in a greenhouse deep in the woods while being pursued by Vassily Krik, where they uncover a long-hidden secret.

Frost, with Valerie's reluctant agreement, attempts to rescue Daniel from Krik's estate, where a tense confrontation reveals Frost's former identity as "Diver," leading to gunfire and a secret witness named Hector. Krik is arrested by authorities, and Daniel's body is later found in Berlin. Meanwhile, Torres uses a deception to bring Platov to Germany, and Sofia must return to Estonia to access a critical master password after the country's communication network is compromised.

With enemy forces on the verge of overthrowing the Estonian government and no support from Langley, Berlin Station launches a last-ditch effort to stop the collapse of the nation.
