Jennifer Cahill and her partner Joshua Kelly are assigned to work with the FBI, to search for a known terrorist who is on their top 10 wanted list and is seen as a credible threat to the city of Chicago. Eli Haswali was last seen on the Magnificent Mile, and it's all hands on deck to track him down. Jennifer goes undercover as a waitress at the Cit Cat Club, after a human trafficking and prostitution ring is suspected, where she meets her temporary partner, Benjamin O'Neil. Benjamin has been working undercover at the club for a while, but has been unable to get close enough to the staff to gain the necessary intel needed, to determine if there is criminal activity going on at the club. While having dinner with Tommy and his brother Kevin, Jennifer meets a young couple from New York state, and later finds them in a situation that could have dire consequences.
