Kyle MacLachlan (of Twin Peaks) stars as David Swain, a wealthy and successful lawyer who heads a high-profile organization called the National Justice Project (commonly abbreviated as "NJP") in the San Francisco Bay Area, along with his lead investigator, ex–police detective Charles Conti (portrayed by Jason O'Mara).

Members of the National Justice Project work pro-bono to overturn wrongful convictions, liberate the falsely accused and discover the identity of those who are really to blame.

The most prominent is Conti's remorse from his time as a police officer, when he caused an innocent suspect's suicide by coercing him to confess to the murder of his family, and how it makes him obsessed with clearing the wrongfully convicted.

Other subplots deals with Swain's uneasy relationship with judicial colleagues and the district attorney's attempts to discredit him, Sonya's personal motivations for clearing the wrongfully convicted—her brother being one of them—and Brianna's reservations and doubts about some of the cases.

The site's consensus states: "In Justice brandishes a refreshingly righteous premise, but this derivative procedural's good intentions can't vindicate the indistinctive casting and uninspired cases".

He wrote: "The chemistry among the leads isn't fully there, and the trail of clues, at least in the opening two episodes, relies on a lot of serendipity and improbable deductive work.
