Prime Video reveals a new four-part original psychological thriller series based on the acclaimed debut novel by Ulf Kvensler.
The series, which shares its title with the book, is set against the vast and unforgiving landscape in Sweden’s Sarek National Park, where a hiking trip among friends takes a dangerous turn.
It is expected to premiere exclusively on Prime Video across the Nordics in 2027.
Two survivors. Two conflicting stories. Only one can be true. When a badly wounded woman is airlifted to safety, she tells police a terrifying story: their group of friends fell under the psychopathic control of a charismatic outsider, leading to manipulation and psychological torture, and death. But just as the case appears closed, an unpredictable twist shatters everything — one of the supposed victims is still alive, and her account of what happened in the wilderness is utterly different.

Sarek stars Felix Sandman (Quicksand), Kitt Walker Johansson (Burden of Justice), Alva Bratt (Barracuda Queens) and Nora Rios (Caliphate), bringing together established and emerging talent in a gritty, high-pace production defined by its claustrophobic tension, unpredictable twists, and layered character work. Måns Herngren (The Restaurant, Adam & Eva) is the series’ conceptualising director and head script writer, co-writers are Amanda Högberg (Diary of a Ditched Girl, Deliver Me) and Axel Stjärne (End of Summer). Henrik Björn (Jordskott) directs one episode.
Sarek is currently in pre-production, with principal photography set to begin at the end of July in Sweden.
The four-part series is produced by Jarowskij/Yellow Bird (part of Banijay Entertainment) and Amazon MGM Studios.
Filmpool Nord are co-producers. Maida Krak serves as producer and Elin Kvist as executive producer.
