Lawyer Diane Lockhart has lost her savings after being affected by a wide-reaching financial scam, and rather than taking her planned retirement, is forced to re-enter the workforce to make ends meet.

Along with Lucca Quinn from her old firm, Diane joins one of Chicago's preeminent law firms that focuses on the fight against police brutality. There, she ends up working with her goddaughter Maia, who recently joined the firm after passing the bar.
