Brooke is a beat cop in New Jersey. She's from a family of cops, starting with her grandfather and she's damn proud of it. When the New York Police Department suffers a horrible cybersecurity breach that reveals all their undercover agents, the Captain of Brooke's precinct asks her if she wants to help.

She is a bit hesitant at first, having never gone undercover, but Captain Bolt reassures her that she has the skills to succeed. When she agrees, Captain Bolt informs her that they are running on very limited information.
