Bull confronts his guilt over closing his psychiatric practice to start TAC when his former patient, a young woman who is a clinical sociopath, goes on trial for killing her brother. When Bull and Benny's client has no memory of the crime due to her mental condition, they enter a "Not Guilty by Reason of Insanity" plea and aim to seat jurors that are sympathetic to mental illness.
Brilliant, brash and charming, Dr. Bull is the ultimate puppet master as he combines psychology, human intuition and high-tech data to learn what makes jurors, attorneys, witnesses and the accused tick. Bull employs an enviable team of experts at Trial Analysis Corporation to shape successful narratives down to the very last detail.
They include his quick-witted ex-brother-in-law, Benny Colón, who plays a defense attorney in mock trials; Marissa Morgan, a cutting-edge neurolinguistics expert from the Department of Homeland Security; former NYPD detective Danny James, the firm's tough but relatable investigator; haughty millennial hacker Cable McCrory, who is responsible for gathering cyber intelligence; and Chunk Palmer, a fashion-conscious stylist and former All-American defensive back who fine-tunes clients' appearances for trial.
In high-stakes trials, Dr. Bull's combination of remarkable insight into human nature, three Ph.D.s and top-notch staff creates winning strategies that tip the scales of justice in his clients' favor.
