In 1981, the radical cleric Omar Abdel-Rahman -- known as The Blind Sheikh -- inspires the assassination of Egyptian president Anwar el-Sadat at a military ceremony. One of the soldiers present is Emad Salem. He swears revenge against the Sheikh.

Cut to: 1990. Salem is retired from the Egyptian army and scratching out a living as an immigrant in New York. NYPD Detective Louis Napoli and FBI Special Agent John Anticev approach him with a potentially life-altering request. Would he be willing to infiltrate a terrorist cell in Brooklyn led by the Blind Sheikh himself? Salem agrees and, relying on his street smarts and military experience, becomes a trusted member of the cell. He’s on the brink of uncovering a major plot when FBI supervisors make a disastrous decision.
