1933. In the months following the Dodson trial, an aimless Perry leans on Della to keep the law firm afloat. While Paul accepts a job from an unlikely source, corrupt oil scion Brooks McCutcheon recruits Det. Holcomb in his quest to reshape the future of Los Angeles.

After a manhunt pegs brothers Rafael and Mateo Gallardo for the McCutcheon murder, Perry initially resists taking the case… until a hunch reels him in. Later, Della goes on a date with a new flame while Paul wrestles with a shocking truth.

As Rafael and Mateo face discrimination from fellow inmates and the court, Perry continues his push for justice, while Della engages the help of socialite Camilla Nygaard. Later, Paul chases leads in the Hooverville, and Perry goes head-to-head with Lydell McCutcheon.

When Paul's explosive discovery blows a massive hole in Rafael and Mateo's story, Perry begins to question his clients' innocence, while Della doubles down on the case.

As the Gallardos' trial nears, Perry attempts to negotiate with the DA. Rafael and Mateo recount the real-life consequences of the McCutcheons' Los Angeles expansion. Later, the pursuit of a lead lands Paul in danger, and Perry makes a convincing demonstration in court.

After he's subpoenaed, Holcomb offers Perry an olive branch. Meanwhile, Della continues to foster her relationships with Camilla and Anita, giving her the confidence to question her first witness - and push the verdict in the Gallardos' favour.

Facing career-ending accusations and potential jailtime, Perry must turn to Strickland to stay ahead of the prosecution - and Lydell. With the Gallardos' fate in the balance, Della presses Hamilton for answers, while Paul and Clara chase a dangerous lead.

As their final day in court nears, Mateo and Rafael prepare for the worst, while Perry, Della and Paul work with an unlikely ally to sway the prosecution's hand. Then, after making his closing arguments, Perry faces the consequences of his relentless pursuit of justice.
