When cybercriminals hack into the U.S. Marshals' Witness Protection database and auction off witnesses' personal details to the highest bidders, the RED Team, led by FBI Agent Sean Nichols, begins a high-stakes chase to find the hacker. But before he can even get started, the first witness is targeted and barely escapes with her life. Sean believes Phantom, an obsessed hacker who previously outwitted the top minds in the field, is behind the attack, and Sean needs this witness's help, as she's the person who has come closest to discovering Phantom's identity.
Trouble is, she's under the care of U.S. Marshal Taylor Mills, and Sean is reluctant to work with the captivating Marshal who knows his deepest secrets. But Phantom seems to be one step ahead at every turn and will stop at nothing to kill the witness. To stop the hacker, Sean and Taylor must learn to trust each other as danger draws ever closer.
