A wave of unexplained murders has terrified Bangladesh, leaving dozens dead and no trace of the killer. When the authorities fail, the country's youngest black-card detective steps in to hunt the shadow spreading fear across the nation. With him stands a sharp-witted lawyer and his closest friend, and an overly determined psychology student who forces her way into the case. Together, the trio dives into a trail of hidden clues, silent newspapers, and a killer who seems always one step ahead. But the deeper they go, the more their buried past begins to surface, threatening to tear open wounds they never wanted to face again. As the murders rise and the darkness tightens around them, the team must confront a truth far more twisted than any of them imagined. This is the beginning of a chase that will rewrite all three of their lives.
