[3] It follows the lives and careers of a team of FBI recruits whilst focusing on the transformation of the U.S. criminal justice system as it is altered by the growing use of artificial intelligence to predict future crimes.

[11] FBI recruits Ashley Poet, Murphy, Tayo Michaels, Daniel Lennix and Hour Nazari meet at Quantico in 2009, each having joined from different backgrounds and for different reasons.

Now separated, Lennix (promoted to Associate Executive Assistant Director) assigns her to spy internally on Nazari, the architect behind a developing criminal database.

Michaels, now the Special Agent-in-Charge in Billings, questions suspected extremist Mark Tupirik at his Montana ranch with his colleague Nunez.

Nazari heads a team developing an advanced investigative database in the FBI Cyber Division, which Poet joins undercover.

A recruit secretly working for him kills several people during a live fire exercise at Quantico, but is shot by a mortally wounded Drew.

Other accomplices disguised as contractors use acid to destroy load bearing structures in the basement of the J. Edgar Hoover Building, collapsing a large section as it is being evacuated.

The recruits visit Martin Luther King Jr.'s childhood home for a seminar on abuse of power, where Michaels meets his future wife, Vivienne.

In 2025, now Executive Assistant Director Michaels advocates rebuilding the agency's entire approach after the failures that led to the attacks by implementing a deep learning AI, pioneered by Amos Garcia.

Garcia suggests his system ignore the presumption of innocence, and be used as a logic gate to initially treat the whole population as guilty before narrowing down suspects using millions of data points.

During tactical and hostage rescue training at Hogan's Alley, the class interpret an end scenario with a fresh human approach.

The AI trial system is used to capture the culprit in one of Poet's unresolved serial murder cases (a disabled long-haul trucker previously disregarded as a suspect) and to secure charges against executives of a powerful Wall Street bank committing white collar crime.

He reluctantly accepts promotion to Director to expand the program, but on the condition he stop investigating his attacker and allow certain people to be exempt from being considered suspects.

The website's critics consensus reads, "Class of '09 hardly flunks out thanks to an impressive cast and intriguing structure, but anemic execution keeps this series far from being valedictorian.
