The border village of Tazeh Qaleh in North Khorasan, Iran has been gripped by fear and unrest. For weeks, the villagers have struggled with an unsettling mystery—one by one, their dogs have been vanishing, only to have their partially devoured remains discovered on the outskirts of the village.

At first, suspicion falls on human involvement, but as the villagers examine the remains and the unusual tracks left behind, it becomes clear that the culprit is not one of them. Panic sets in when they encounter a fierce predator that shows no hesitation in standing its ground. Many believe this relentless hunter is the very creature responsible for the disappearances—a beast that refuses to leave and has already claimed more than half of the village’s dogs.

Rather than taking matters into their own hands, the villagers choose patience over vengeance. They reach out to environmental authorities, seeking a solution that aligns with both the law and ethical responsibility. A team of wildlife experts arrives, launching a tense ten-day operation to identify, track, and capture the elusive animal. After repeated failed attempts, they finally succeed in capturing an aged predator, its frailty offering clues to the desperate shift in its hunting behavior.

Just when it seems the mystery has been solved, an unforeseen and tragic event unfolds—one that casts a dark shadow over the fragile balance between humans and nature.
