[2][3] A year after the series finale of The Good Wife, an enormous financial scam destroys the reputation of young lawyer Maia Rindell and wipes out the savings of her mentor, Diane Lockhart.

The two are forced out of Lockhart, Deckler, Gussman, Lee, Lyman, Gilbert-Lurie, Kagan, Tannebaum, & Associates and join Diane's former employee Lucca Quinn at Reddick, Boseman, & Kolstad, a prestigious African American–owned firm making waves by taking on Illinois police brutality cases.

The show initially deals primarily with the storylines of its three female leads – Diane, Lucca, and Maia – and contains considerable political and social commentary, exploring topical issues such as the alt-right, the MeToo movement, online harassment, and fake news.

Lucca Quinn, a former employee of Diane's, has found firm footing at Reddick, Boseman & Lockhart and is a rising star on the partner track, balancing her dedication to her work and a romantic entanglement with US Attorney Colin Morello, a frequent opposing counsel.

Meanwhile, Maia, Diane's goddaughter, is trying to get her legal career off to a good start, while coming under pressure from the FBI over alleged involvement with her father's Ponzi scheme.

The firm is also joined by Marissa Gold, a recurring character on The Good Wife, an intelligent and self-assured young woman with Democratic Party connections who becomes their newest private investigator.

Like The Good Wife, the show makes use of an extensive cast of supporting characters, including a recurring stable of opposing counsel, clients, police officers, FBI agents, judges, and politicians.

The segments have drawn comparisons to the series Schoolhouse Rock!, albeit discussing topics such as the impeachment process, non-disclosure agreements, and Russian trolls.

Coulton remarked he shared the Kings' "sensibility of really liking to mess with the form itself and poke through the fourth wall a little bit", and has received a relative amount of creative freedom in regards to the content of these interludes.

[6] The day after, The Hollywood Reporter announced that Delroy Lindo had been cast as "Robert" Boseman, an attorney who starts poaching Diane's associates and clients.

[20] It was confirmed on November 11, 2016, that Zach Grenier, Jerry Adler, and Carrie Preston would be returning as guest stars, reprising their roles of David Lee, Howard Lyman, and Elsbeth Tascioni respectively.

[28][23] On November 18, 2016, it was announced that Justin Bartha had been added as a series regular as Colin, a rising star in the US Attorney's office and love interest to Lucca.

[56] In March 2022, it was announced that Andre Braugher had joined the cast as a new series regular while Alan Cumming would reprise his role as Eli Gold from The Good Wife as a guest star for the sixth season.
