Months after the end of the Dodson trial, Perry's moved off the farm, ditched the milk truck, he's even traded his leather jacket for a pressed suit. It's the worst year of the Depression, and Perry and Della have set the firm on a safer path pursuing civil cases instead of the tumultuous work that criminal cases entail. Unfortunately, there isn't much work for Paul in wills and contracts, so he's been out on his own. An open-and-closed case overtakes the city of Los Angeles, and Perry's pursuit of justice reveals that not everything is always as it seems.

As Perry grapples with a new career, Della keeps the firm afloat; Paul accepts a questionable job; Holcomb partners with a powerful ally.

While the DA focuses on two brothers from Hooverville as their prime suspects, a discovery pushes Perry closer to the case.

Given three weeks to work the case, Perry and Della try to build a defense for their clients, while Paul chases leads in the Hooverville.

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 β and push the verdict in the Gallardos' favor.

Facing career-ending accusations and potential jailtime, Perry must turn to Strickland to stay ahead of the prosecution β and Lydell. With the Gallardos' fate in the balance, Della presses Hamilton for answers, while Paul enlists Clara to infiltrate a wealthy white suburb in pursuit of the truth.

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.
