A Bulgarian crime drama set in the Rhodope Mountains is gaining international attention with its atmospheric blend of local folklore and ritualistic mystery. The series, titled after a nearby cave known for its underground waterfall, follows police chief Filip and state security officer Miya as they investigate a string of ritualistic murders amid swirling rumors of supernatural involvement.

The show features performances by Vladimir Karamazov and Teodora Duhovnikova in the lead roles of Filip and Miya, who develop a strong working partnership while navigating the region’s dense forests and rugged peaks. The mythology-rich setting of the Rhodope Mountains serves as a backdrop for the complex investigations and adds a distinctive cultural layer to the storyline.

The first series, which aired in Bulgaria, was well received domestically, prompting the production of a second season. In the follow-up installment, scheduled to debut on Channel 4, the duo confronts the killing of a local judge, another case that appears linked to ritualistic practices.

The program blends elements of crime procedural drama with mystical elements rooted in local legend, creating a tense narrative that explores themes of belief, justice, and the unknown. Its availability on Channel 4 marks the series’ expansion to an international audience interested in crime dramas with unique cultural contexts.
