Karen Sisco

When a suave con artist who bilks women out of their fortunes manages to slip away from Karen the minute he's off the plane, she's humiliated but determined to bring him in, despite the fact the FBI has ordered her off the case. Meanwhile, a former mob accountant suddenly returns from hiding in the witness protection program, putting his — and Karen's — life in jeopardy; and Marshall is unhappy to find that Karen's old boyfriend, a married FBI agent, is back on the scene.

Karen reluctantly teams with Konner, a legendary marshal new to the Miami office, to hunt down three parolees who have gone on a crime spree, unaware that the cons — all former gang members — have a link to Konner's past and that he intends to mete out his own deadly brand of justice.

Karen must protect a counterfeiter who claims they went to high school together and appears to be the target of a mob boss. Meanwhile, Marshall's past comes to haunt him when an ex-con decides to settle a very old score.

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.

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.

While visiting the bank, Marshall and Karen are taken hostage. Karen and Marshall try to save the situation from the inside, while Karen's boss, Amos Andrews, tries to hold back the FBI. The FBI agent on the scene, Gil Bellows, is a little to eager to storm the bank, which might jeopardize the lives of the hostages.

A young girl witnesses the murder of her guardian (a snitch) by a drug dealer, and must be protected by Karen.

Karen goes undercover as an escort, and investigates designer drugs.
