Barcelona-based Limonero Films has nabbed world rights to distribute “Bock Saga,” an original, four-part true crime series produced by Finnish group Parad Media.

The cult-related series, which premieres on Finnish broadcaster YLE on July 27, has already pre-sold to NRK in Norway, Swedish broadcaster SVT and Denmark’s DR.

The series examines the enigmatic story of the followers of Ior Bock, a self-proclaimed mystic who claimed his descendants were custodians of Finland’s ancient pagan culture – stories that formed his so-called Bock saga.

From trance parties in Goa to an underground temple in Finland rumored to contain a treasure worth €20 billion ($23 billion), the series “unravels a surreal journey of faith, obsession, and conspiracy,” Limonero Films stated.

Blending real-time investigations, archival footage and animation, “Bock Saga” explores what happens when myth and reality collide in the ultimate search for truth.

“I am so proud to present the bizarre story of Ior Bock and his disciples to the world,” said Axel Högström, CEO and producer at Parad Media.

“We have been working on this documentary for five years now, tracing the ripples of the alternative creation myth that Bock proclaimed. The production has taken us all over the world — from the dark woods of Finland to sex parties in Berlin, to the slums of Goa, and all the way to sunny California.

“It is a truly compelling story that transcends both space and time. For me, ‘Bock Saga’ is the ultimate proof that truth really is stranger than fiction, and I am very happy that Limonero helps us share this once-in-a-lifetime gem with the international audiences.”

Limonero Films founder and CEO Pamela Martínez Martínez added: “True crime, cults, eccentric characters, a treasure — it has all the ingredients to be a hit.”

The boutique distributor will launch the series at the upcoming Sunny Side of the Doc in La Rochelle, France.
