In the heart of Zagreb, four strangers - each worn down by the pressures of modern urban life - are brought together by a violent incident that ends in death. What begins as an act of self-defense, quickly spirals into a dangerous cover-up, drawing them into the crosshairs of a powerful crime boss and a relentless police investigator. As their lives become increasingly entangled, these ordinary individuals must confront the consequences of their actions and decide whether to fight back or disappear.

Success is a gripping, character-driven thriller that explores the fragility of morality under pressure, the complexity of human connection, and the harsh realities of life in a city where justice is elusive and survival is everything. With its layered storytelling and raw emotional depth, the series offers a powerful reflection on societal obligation, personal responsibility, and the cost of silence.
