From Wolf Entertainment and Emmy Award-winning Executive Producer Dick Wolf, FBI is a fast-paced drama about the inner workings of the New York office of the Federal Bureau of Investigation. This elite unit brings to bear all their talents, intellect and technical expertise on major cases in order to keep New York and the country safe.
Born into a multigenerational law enforcement family, Special Agent Maggie Bell commits deeply to the people she works with as well as those she protects. Her partner is Special Agent Omar Adom "OA" Zidan, a West Point graduate via Bushwick who spent two years undercover for the DEA before being cherry-picked by the FBI. Also on the team is Special Agent Stuart Scola, an Ivy League-educated Wall Streeter-turned-FBI agent. His new partner is Special Agent Eva Ramos, a former prosecutor with a background tackling violent crime and narcotics cases.
Overseeing them is Special Agent in Charge Isobel Castille, who operates under intense pressure and has undeniable command authority. The team also includes Assistant Special Agent in Charge Jubal Valentine, the nerve center of the office, whose ability to easily relate to and engage with both superiors and subordinates makes him a master motivator. These first-class agents tenaciously investigate cases of tremendous magnitude, including terrorism, organized crime, and counterintelligence.
CBS's FBI stars Missy Peregrym (Special Agent Maggie Bell), Zeeko Zaki (Special Agent Omar Adom "OA" Zidan), Jeremy Sisto (Assistant Special Agent in Charge Jubal Valentine), Alana De La Garza (Special Agent in Charge Isobel Castille), John Boyd (Special Agent Stuart Scola), and Juliana Aidén Martinez (Special Agent Eva Ramos). Stemming from Universal Television, a division of Universal Studio Group, in association with Wolf Entertainment and CBS Studios, the show's executive producers include Dick Wolf, Mike Weiss, Alex Chapple, Amanda Slater, Rick Eid, and Peter Jankowski.
