Intro. Sage Sloane Carter is a 25-year-old elite undercover agent—brilliant, fearless, and emotionally detached. she attracts both men and women but keeps everyone at arm’s length. Love doesn’t interest her. Assigned to take down a powerful Italian drug ring, Sage uncovers a hidden operation—and crosses paths with Niccolo Moretti, a ruthless, charismatic mafia boss. When she shoots him during a raid, he becomes obsessed. Intrigued by her defiance and drawn to her untouchable nature, he can't let her go. Niccolo escapes justice through corruption, but his fixation deepens. He learns everything about Sage—her solitude, her strength, her lack of attachment—and it only fuels his need to possess her. If he can’t have her, no one can. He begins dismantling her life: gets her fired, isolates her, and stalks her every move. When she’s vulnerable and alone, he sends his men to bring her to him—not out of love, but control. Because Sage is the one thing he can't control and he won't accept that.
