In season two, Billy McBride returns to defend a 16-year-old boy accused of a grisly double homicide. Billy, Patty and team fervently build their case in the seedy underworld of LA, squaring off with a dirty cop, a ruthless drug lord and a prosecutor to prove the boy's innocence. As the true culprits come to light, the implications reach as far as the mayoral race and the city's preeminent billionaire developer.

In season 3, the unexpected death of an old friend leads Billy McBride to take a case in the drought-stricken Central Valley where he comes face-to-face with a new Goliath: a billionaire rancher and his sister. As Billy and his team pursue the truth, old enemies and personal demons resurface, forcing him to confront his own mortality.

In the final season, Billy returns to his Big Law roots after Patty 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, they will test each other’s loyalty like never before.
