Six months after Cassie Morgan faced The Assassin, it’s time for her to get back to work. After a break from the FBI, Cassie arrives to find her first assignment: the death of her former informant, Maria Floures.
 
In order to bring justice to Floures, Cassie is assigned to work with a group of DEA agents investigating a drug ring that has ties to Floures and the man suggested of murdering her. One of those DEA agents is Seth Edwards, a man who recently stood Cassie up on a blind date.
 
While she tries to ignore the tension between her and Seth, the two must work closely together when Seth goes undercover to infiltrate the drug group tied to Floures. Once he’s in, Cassie realizes that this group may be connected to more than just Floures. As they peel back the structure of the drug ring, Cassie realizes a figure from her past is at the head of it, and Cassie may have just been double played.
