Bull stars Michael Weatherly as Dr. Jason Bull in a drama inspired by the early career of Dr. Phil McGraw, the founder of one of the most prolific trial consulting firms of all time. 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 former brother-in-law, Benny Colón, a lawyer who acts as defense attorney in the company's 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 lineman who fine tunes clients' appearances for trial. In high-stakes trials, Bull's combination of remarkable insight into human nature, three Ph.D.'s and a top-notch staff creates winning strategies that tip the scales of justice in his clients' favor.
When Bull joins the district attorney in a case against Kara Clayton, who claims she killed her billionaire husband in self-defense, tensions run high when he learns that his on-again, off-again romantic interest, Diana Lindsay, is defending the widow. Also, Chunk makes a decision about his future.
The DA's office asks Bull to assist them in their prosecution of a fraternity when a pledge accidentally drowns during a hazing incident, but his efforts may be derailed when the students close ranks to stonewall him.
