Once a federal undercover operative, Lana grew up in a Chicago orphanage and now sells flowers under a new name. After a year of gentle courtship from the billionaire Ethan, she steps into a lavish church ceremony. Then her vows are interrupted: the ceremony is a dark-web hunting broadcast, the guests are financiers and hunters, the downtown blocks are sealed, and Lana is marked as prey. Whoever kills her within twenty-four hours collects a bounty of five million dollars.
Ethan's four groomsmen lead the hunt. Running for her life, Lana crosses paths with Jax, an ex-soldier turned tracker, and learns that his sister Mia is trapped in the hunt too, drawn in by a part-time scam run by a middleman named Kian. The two of them band together to survive, and they are pulled deeper into a ruthless game with the people who control the hunt.
