Picking up one year after the events of the final episode of "The Good Wife", an enormous financial scam has destroyed the reputation of a young lawyer, Maia Rindell, while simultaneously wiping out her mentor and godmother Diane Lockhart's savings. Forced out of Lockhart and Lee, they join Lucca Quinn at one of Chicago's preeminent law firms.

Diane Lockhart watches the inauguration of Donald Trump in stunned silence and is motivated to make a change. She plans for her retirement and signs an exit agreement with her firm.
She meets with friends to celebrate, including the Rindell family, headed by the powerful and respected Henry Rindell, a financial consultant who has invested money for many prominent businesspeople in Chicago, including Diane and many of her clients.
Diane is godmother to Rindell's daughter, Maia, who has just passed the bar, and through Diane's connections, has secured a starting position at the firm.
Diane heads what will be her final case at the firm, a police brutality charge, in which she is representing the state. Opposing her is Adrian Boseman, the head of a rival firm, hoping to secure a large settlement for his client. Boseman is assisted by Lucca Quinn, who has joined Boseman's firm after leaving Diane's employ. Before Diane can close the case, Henry Rindell is arrested for orchestrating an elaborate ponzi scheme, and Diane finds herself broke and unable to follow through with her retirement.
However, when she attempts to return to the firm, she is rebuffed. Joining another firm also proves difficult, as Diane is seen as complicit in the scam, having directed many of her clients to invest with Rindell. Diane is told that her assets may be seized as evidence, and she is advised to divorce her husband, Kurt, to prevent his assets being seized as well. Having separated from Kurt after the discovery of his affair, Diane puts the option to him, but he refuses to file for divorce, still hoping for a reconciliation.
Meanwhile, Boseman realizes that there is an opportunity to gain Diane's services for a fraction of her value, and he offers her a junior partner position at his firm. With few other options, Diane accepts Boseman's offer, and when Maia is fired, in part due to her father's financial scandal, Diane brings her along to her new firm.
