Amazon Prime Video has released the official trailer for the fourth and final season of their original series, “Goliath.”

In the final season, Billy Bob Thornton returns to his Big Law roots after Patty (Nina Arianda) takes a job at a prestigious white-shoe law firm in San Francisco.  

Together, they try to take down one of America’s most insidious Goliaths: the opioid industry. As Billy deals with his own chronic pain and Patty can’t shake the feeling she’s being used, their loyalties will be tested, putting their partnership on the line. 

In a world where money can buy anything, even justice, they’ll have to risk everything to do what’s right. 

Goliath” stars Billy Bob Thornton, Nina Arianda, Tania Raymonde, Diana Hopper, Julie Brister, Bruce Dern, Brandon Scott, Jena Malone, and J.K. Simmons.
