Captain Lina Savage leads an elite task force hunting sex traffickers across the darkest corners of the world. With her K-9 partner Tango at her side, Lina has spent years turning war-hardened instincts into weapons against those who prey on the vulnerable. But when a mission ends in tragedy and one of their own is taken, the fight becomes personal. As the team races across continents to dismantle a ruthless trafficking network, every step forward reveals a deeper and more dangerous enemy. Lina must confront not only the criminals they hunt, but the ghosts of the battlefield she thought she left behind. In a world where justice is never simple and survival comes at a cost, Lina will learn that some battles echo long after the gunfire fades—and the price of protecting the innocent may demand everything she has left.
