Dana comes to ADA Gabriel Lowan, requesting help on a case. He calls in Catherine and her partner, Tess Vargas. Dana is tracking a group of thieves. One of the members figured out Dana was following her, and tried to kill her. Dana shot back, and killed the thief, Mara. Dana asks Catherine to go undercover in place of Mara in order to find out what the thieves are after. When Gabe questions why she's chosen Catherine, Dana reveals she knows about Catherine's father, FBI Agent Robert Reynolds, who was recently sent to jail by Gabe, Catherine, and Tess; she feels like she can trust them if Catherine is willing to put her own father in jail. Though Gabe thinks it's too dangerous, Catherine agrees to help.
