The FBI: Most Wanted Plot, Courtesy of CBS:

FBI: Most Wanted is a high-stakes drama that focuses on the Fugitive Task Force, an elite unit that relentlessly pursues and captures the notorious criminals on the Bureau’s Most Wanted list. The team’s charming but formidable new leader is Supervisory Special Agent Remy Scott, who started his career in the New York FBI field office before rising through the ranks of the Bureau in Philadelphia and Las Vegas.

The team includes Special Agent Sheryll Barnes, a former NYPD detective and forensics expert who is raising two young children with her wife; Special Agent Hana Gibson, a gifted millennial computer whiz with a sharp wit and mad hacking skills; Special Agent Kristin Gaines, a Navy veteran who became a star in the FBI’s Miami Field Office as a result of her dogged pursuit of cold cases; and their newest member, former New Orleans cop-turned-junior detective Ray Cannon, who was recently working Violent Crimes in Albany after following in his retired FBI agent father’s footsteps and graduating at the top of his class at Quantico last year.

Always in the field and always on the run, FBI: Most Wanted is a weekly adrenaline shot about the thrill of the chase.
