‘Babylon Berlin’ Seasons 1 to 4 Recap: Every Twist You Need Before the Final Season Airs

‘Babylon Berlin’ has spent nearly a decade turning Weimar era police work into some of the most obsessively plotted television around, and with the fifth and final season now underway, plenty of fans are scrambling to remember exactly how Gereon Rath and Charlotte Ritter got here. The series, based on Volker Kutscher’s novels, follows the pair as they claw through corruption, addiction, and political extremism in late 1920s and early 1930s Berlin.

Between the drug fueled cabarets, Soviet gold trains, and a literal moon rocket, keeping the timeline straight across four seasons is no small task. Here is a refresher on where ‘Babylon Berlin’ left off before the story barrels toward Hitler’s rise to power.

A Recap of Gereon and Charlotte’s Journey

Inspector Gereon Rath is introduced as a shellshocked World War I veteran who is transferred from Cologne to Berlin and struggles with morphine dependence tied to his war experiences, particularly the guilt he carries over losing his brother. That guilt becomes even messier once his sister in law Helga enters the picture as his secret lover.

Charlotte Ritter starts out as a resourceful young woman from Neukölln who works occasionally at the Moka Efti cabaret while holding down a job as a police clerk, all while dreaming of becoming the first female homicide detective in Berlin police history. Her arc across the early seasons is essentially a slow, hard fought climb up the ranks of a police force that does not want her there.

Season one centers on a stolen pornography ring investigation that spirals into a much bigger conspiracy involving a dangerous web of shadows tied to a Soviet gold shipment hidden aboard a freight train. Along the way, Svetlana Sorokina, a White Russian countess performing in drag at the Moka Efti, betrays the Trotskyist revolutionary Alexei Kardakov to the Soviet embassy, which leads to a massacre of his followers in a basement headquarters.

Seasons two and three widen the lens considerably. Helga becomes a much bigger presence in the story, complicating Gereon’s life while getting tangled in other plotlines, and a string of murders threatens to derail a film production financed by rival gangsters, dragging political and financial players into the fray.

Weimar Berlin Underworld Plot Threads that Carried into Season 4

By the time season four opens on New Year’s Eve heading into 1931, the show’s underworld has become its own battlefield. Berlin’s ringvereine, the loosely allied gangs who profit off boxing and betting, are thrown into chaos after someone starts fixing fights and framing Weintraub, the gang leader who inherited control after the death of the Armenian.

That underworld chaos collides with Gereon’s own unraveling, since he has joined the SA stormtroopers and gets arrested after taking part in an anti-Jewish pogrom, a development that leaves Charlotte, now firmly anti-Nazi, shocked when she witnesses his arrest. It is a stunning turn for a character fans had followed for three seasons as a flawed but sympathetic cop.

Meanwhile, industrialist Alfred Nyssen keeps pushing his own dangerous ambitions. Nyssen is building rockets under the guise of a moon mission, while Nazi sympathizer Colonel Wendt of the Berlin Political Police quietly pushes him toward weaponizing the technology instead, despite the restrictions of the Versailles treaty.

A new arrival named Abraham Goldstein also complicates matters when he shows up in Berlin as the secretive organization known as the White Hand passes judgment on a criminal, right as Rath investigates a fixed boxing match. Critics largely responded well to this messier, more sprawling structure, with one review calling season four as densely plotted as seasons one and two and a return to form after a slightly disappointing third season.

Charlotte Ritter and Gereon Rath’s Fractured Relationship by Season 4’s Finale

The season four finale pushes nearly every storyline to a breaking point at once. Stennes and the SA seize the Angriff building and Stennes challenges Gereon to execute a local NSDAP leader, and when Gereon refuses, Stennes exposes him as a traitor and orders his death, only for Moritz to rescue him.

Elsewhere, the season closes on an unsettling and ambiguous note. The season ends on a Gainax style finish centered on Dr. Schmidt and the patients of an asylum, while the final shot shows Charlotte jolting awake from what plays like a nightmare. It is the kind of unresolved cliffhanger that has defined the show since season one.

Political tension only escalates from there, since the season also delivers a jarring shock when the SS, acting on Colonel Wendt’s orders, open fire on Stennes’ men with rifles instead of engaging in the physical brawl he expected. That single moment crystallizes just how far the Nazi apparatus has already outpaced the street level power struggles the characters had been fighting for years.

By the time the credits roll on season four, Gereon’s morphine addiction, Charlotte’s fight to be taken seriously as a detective, and the slow motion collapse of the Weimar Republic have all folded into one increasingly claustrophobic story.

‘Babylon Berlin’ Final Season Details Fans Should Know

The wait for closure is finally over. Production coverage confirms the fifth and final season reunites writer director trio Tom Tykwer, Henk Handloegten, and Achim von Borries, with the season premiering on Germany’s ARD on September 10 and set to roll out internationally to more than 140 territories in the following months.

The story picks up almost immediately after where season four left off. The final season covers the five short weeks in February 1933 when German democracy collapsed, beginning with Adolf Hitler being named Reich Chancellor on January 30, 1933. Familiar faces are expected back too, including Alfred Nyssen, police photographer Reinhold Gräf, Gereon’s former lover Helga Rath, and journalist Samuel Katelbach.

The finale is also expanding well beyond the show itself. According to an exclusive report from The Hollywood Reporter, the creators are launching a companion video game developed with SWR X Lab, a making of documentary from director Christian Jakob, and a separate audio drama series set within the Babylon Berlin universe.

After everything Gereon Rath and Charlotte Ritter have survived across four seasons of betrayal, addiction, and rising fascism, which storyline from ‘Babylon Berlin’ do you think deserves the most satisfying send off in these final episodes.
