Season 4
🎬 21 Episodes 📅 2021 ⏱ 43 min
New York is more than a busy backdrop here; it is the pressure point for federal cases that reach beyond local policing, from organized crime and kidnappings to terrorism threats and high-risk investigations. Maggie Bell and Omar Zidan work within a team that relies on field response, fast analysis, and coordination between agents and specialists, where force alone is never enough. FBI builds its appeal as a procedural: each case begins with a direct threat, then becomes a race to uncover the truth before the damage spreads.
