In the mid-19th century, near the borders of a weakening Ottoman Empire, Hadži Trifun is a powerful, wealthy Serbian Christian merchant who aggressively navigates complex political alliances with Turkish begs to protect his family's vast influence. Desperate to secure a lasting lineage, Trifun orchestrates a series of cold, strategic arrangements, forcing his sons into financially beneficial marriages and controlling the lives of the women under his authoritarian roof. However, his ruthless maneuvers unleash a multi-generational curse of violent impulses, madness, and deep psychological trauma—termed "impure blood." As the decades progress, his descendants—including his fiercely independent daughter-in-law Tašana, his sister Cona, and ultimately his beautiful but tragic granddaughter Sofka—become hopelessly trapped in a claustrophobic web of forced marriages, unrequited desires, destructive extramarital infidelities, and severe domestic isolation as their family empire slowly collapses into ruin
