The acclaimed French crime drama Astrid (known in France as Astrid et Raphaëlle) returns with its gripping fifth season, now streaming in the United States through PBS Passport and the PBS Masterpiece channel on Amazon Prime Video. The series, which blends sharp forensic detail, intellectual puzzles, and heartfelt character development, continues to captivate audiences with its unique lead duo: Astrid Nielsen, a brilliant autistic archivist with an extraordinary memory and pattern-recognition ability, and Raphaëlle Coste, a tough, intuitive police commander who relies on Astrid’s insights to crack the most baffling cases.
Season 5, consisting of eight episodes, premiered in France on France 2 in late 2024 and early 2025, breaking audience records with an average of over 6 million viewers per episode. The season made its U.S. debut in early 2026 via PBS platforms, allowing American fans to dive into the new mysteries with English subtitles. Episodes are available for streaming on demand through PBS Passport (for members) or the PBS Masterpiece add-on on Amazon Prime Video, offering the flexibility to binge at leisure.
The core premise remains unchanged: Astrid Nielsen (Sara Mortensen), a reserved, highly intelligent woman with autism who works in the judicial police archives, possesses an almost photographic memory and an uncanny talent for spotting connections others miss. She teams up with Commander Raphaëlle Coste (Lola Dewaere), a no-nonsense detective whose impulsive nature balances Astrid’s methodical approach. Together, they solve complex crimes that stump conventional investigators, all while navigating personal challenges and the evolving dynamics of their partnership.
Season 5 pushes the boundaries further, delivering some of the most ambitious and emotionally charged cases yet. The opening two-parter, “You Only Die Once” (“On ne meurt qu’une seule fois”), kicks off with the murder of a seemingly anonymous Canadian woman poisoned by an exotic snake venom dart while eating lunch by the Seine. Astrid quickly recognizes the signature of a long-dormant professional assassin known as “The Reptile,” pulling the duo into a dangerous web involving organized crime and international intrigue. The investigation forces Astrid and Raphaëlle into the unfamiliar territory of espionage, with French and American intelligence agencies recruiting them as reluctant spies and double agents in a tense political game.
Subsequent episodes explore equally intricate mysteries. One case involves a murdered monk whose death reopens a 1996 monastery killing tied to a Tibetan lama, blending spiritual ritual with cold-blooded murder. Another centers on an archaeologist found dead in an Aztec-style ritual, his heart placed in a sacred urn, raising questions about cultural appropriation, revenge, and hidden historical grudges. A film-set accident—where a famous actor is killed by a blank bullet—turns out to be deliberate murder, leading to suspicions of a vengeful director targeting the man who had an affair with his wife.
The season also delves into personal stakes. Raphaëlle faces significant life changes, including emotional turmoil and shifting relationships, while Astrid finds herself drawn into deeper danger. The return of a shocking figure from their past—Lamarck—tests their bond like never before, forcing both women to confront trust, vulnerability, and the lines between logic, instinct, and emotion. Recurring characters such as Nicolas (Benoît Michel), Norah (Sophia Yamna), Commissioner Carl Bachert (Jean-Louis Boy), and others add depth to the ensemble, with subplots exploring loyalty, grief, and the personal cost of their work.
What sets Astrid apart is its thoughtful portrayal of autism through Astrid’s character. Sara Mortensen delivers a nuanced, dignified performance that avoids stereotypes, showing Astrid’s extraordinary gifts alongside her challenges with social cues and sensory overload. Her partnership with Raphaëlle—initially professional, gradually deepening into genuine friendship—remains the emotional core. Lola Dewaere brings fire and vulnerability to Raphaëlle, making her a compelling foil: impulsive yet deeply caring, street-smart yet capable of profound empathy.
The series excels at blending procedural elements with character-driven storytelling. Each case is meticulously researched, showcasing real forensic techniques, psychological insights, and cultural details. The Paris setting is beautifully captured—rain-slicked streets, historic buildings, quiet archives—creating a moody, atmospheric backdrop that enhances the suspense.
Season 5 has been praised for its ambitious storytelling, darker tone, and emotional depth. The espionage arc raises the stakes, while ritualistic murders and personal betrayals keep the tension high. Fans appreciate how the show respects Astrid’s autism without defining her solely by it, and how Raphaëlle’s growth adds layers to their dynamic.
For U.S. viewers, the PBS Masterpiece airing (with episodes available via Passport and Prime Video) offers high-quality subtitles and the familiar Masterpiece branding. The full-season availability allows binge-watching, while the weekly BBC One-style airing preserves suspense for those who prefer it.
With eight compelling episodes, strong performances, and a perfect mix of intellectual puzzles and heartfelt moments, Season 5 of Astrid solidifies its place as one of the most engaging crime dramas on television. Whether you’re new to the series or a longtime fan, this season delivers the intellectual depth, suspense, and character richness that make Astrid so special.
The cases are intricate, the stakes are higher, and the bond between Astrid and Raphaëlle is tested like never before. Dive in—Paris is waiting, and the mysteries are calling.
