What Is Leeches About?
The premise of Leeches in 227 words, with nothing given away. The full story follows below.
In a Serbia teetering on the edge of upheaval, the streets pulse with whispered dissent and the weight of an uncertain future. Government edicts clash with everyday conversations, and an ever‑present sense of surveillance colors every public square and cramped apartment alike. The nation’s turmoil is not just political—it seeps into the very fabric of daily life, turning ordinary moments into questions of loyalty, truth, and survival.
At the heart of this restless landscape is Petar Miric, a writer whose words have always chased the edge of what can be said aloud. As the ruling regime tightens its grip, his essays and stories become increasingly controversial, drawing the wary eyes of the State Security Authority. Petar’s once‑steady confidence begins to erode, replaced by a gnawing paranoia that makes even familiar faces seem foreign. His quest for understanding morphs into a desperate search for the hidden currents that shape the chaos surrounding him.
The film drifts between the claustrophobic corridors of a surveilled city and the expansive, often oppressive interior of Petar’s mind. A tense, almost cinematic atmosphere hangs over every interaction, as the unseen forces that govern society press ever closer to the surface. This is a story of a man wrestling with doubt, of a nation caught between hope and fear, and of the fragile line between reality and the paranoia that threatens to consume it.

Spoilers ahead
Starring Lazar Ristovski as Stjepan Stroh, Annamaria Serda as Sekretarica, and Iva Mihalić as Svetlana, the film centers on a college swim team that looks for every edge to win. In a bid for a stronger edge, the group starts using anabolic steroids to boost performance. During a day trip to a local lake, several swimmers unintentionally come into contact with leeches that feed on the steroids in their blood. The leeches are swept down a shower drain and begin to grow to terrifying, oversized proportions, returning to feed again and again.
With a string of deaths among teammates and a college administrator, the surviving members and one of their girlfriends hatch a plan to eliminate the threat. Their method is to lure the leeches to the campus swimming pool by using one swimmer as bait, then to electrify the pool to fry them. The plan faces a severe setback when the team coach, who has been infected by a leech, attacks the group and delays the moment of electrification, allowing the leeches to kill one more swimmer. In the end, the switch is thrown, the pool is fried, and the threat is neutralized.
Yet the ending reveals a disturbing twist: a surviving swim team member, in true mad scientist fashion, is shown to have had a hand in creating the leeches and is revealed to have breeding stock left behind for possible future experiments.
