In the final season, after Patty takes a job at a prestigious white-shoe law firm in San Francisco, Billy returns to his Big Law roots. Together, they try to take down one of America's most insidious Goliaths: the opioid industry.

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 season two Billy McBride returns to criminal defense, taking on a grisly double murder case in Venice. His client is a 16-year-old boy — and Billy's damn sure he's innocent. Billy and his team fervently build their case in the seedy underworld of Los Angeles, squaring off with a dirty cop, tight-lipped gangbangers, and a prosecutor with a point to prove. As the murders' true culprits come to light, the implications reach as far as the mayoral race — and the city's preeminent billionaire developer.
