Karen goes undercover as an escort, and investigates designer drugs.
A young girl witnesses the murder of her guardian (a snitch) by a drug dealer, and must be protected by Karen.
Karen is assigned to track down a fugitive accountant on the lam for murder and the theft of hundreds of thousands of dollars from his high-end fashion boss. Meanwhile, Marshall meets an attractive woman who wants him to investigate her husband's infidelity.
It looks like Karen's budding romance with a sexy Miami Marlins pitcher will never get to third base, as her assignment — to bring in a prison escapee determined to be reunited with his stripper girlfriend — wreaks havoc with her personal life.
As a U.S. Deputy Marshal, based on Miami, Florida's Gold Coast, Karen must deal with the underbelly of South Beach nightlife and Palm Beach high life while tracking down fugitives. She also struggles to win the respect of her fellow officers. Karen occasionally gets advice from her father, a retired Miami police officer turned private investigator, who is Karen’s confidant, counselor, and confessor.
