As a hurricane bears down on Palmetto, a steely Desna proceeds with the plans for her wedding day, keen for the opportunity to settle all scores. Opposing forces converge at a lavish golf resort, each determined to prevail against the others, but will Desna and crew survive the storm?.

As Desna plans for a big day, she realizes she can play a two-faced #bossbitch better than the rest of them. Meanwhile, after getting a disturbing message from Marnie, a reeling Polly gets an unexpected visit from her long-lost sister that sends her spinning out of control. In the meantime, Uncle Daddy and Roller join forces with their Dixie Mafia brethren and make a plan to take out the Russian and Haitian mafias for good.

After a harrowing experience, Desna is offered a deal with the Russian devil, aka Zlata, that's more intriguing than nail art on acrylics. Meanwhile, Polly and Quiet Ann get dealt some hard-ass betrayal from their baes while Jenn's affair comes back to haunt her.

When Desna with the help of Uncle Daddy and her crew (Dean Norris) plots revenge on those who betrayed her, she realizes that vengeance comes at a high cost.

Faced with an agonizing dilemma, Desna and Dean take a road trip to seek guidance from a beloved childhood mentor. Back in Palmetto, Jenn must lean on Polly and Quiet Ann for help with a personal crisis. Meanwhile, Virginia struggles to run the salon by herself.

Desna continues to grow closer to Zlata, despite the crew's increasing concern - as her relationship with Dr. Ruval intensifies. Meanwhile, Dean gets an opportunity to showcase his talents and Uncle Daddy gets his mojo back.

In an attempt to cozy up to Ruval's mother, Desna puts together a spa day for her and a couple of young girls from his charity; Quiet Ann gets a surprise visit from her brother, who convinces her to attend a family dinner.

Desna's relationship with Ruval deepens when he introduces her to his mother, Matilde; Polly grows concerned when Marnie continues to pull away from her; Jenn, still depressed by Bryce's recent indiscretion, falls off the wagon.

Desna, now pinned under the stiletto-tipped nail of Riva's sister, Zlata, must come up with an idea to generate more customers for the clinic. Meanwhile, Quiet Ann helps Dean and Virginia get to a very important appointment, which leads to an unexpected moment of joy.

Desna and the girls struggle to keep their hope alive while still working under the thumb of the new Russian regime, spearheaded by Riva. A blissful Desna remains in the dark about her gangster/gyno boyfriend, Ruval. Virginia tells Dean that she's pregnant with his baby. A newly domesticated Polly is jubilant when tasked with being a madam for an all-male dance troupe. Meanwhile, a depressed Uncle Daddy, still reeling from the loss of his beloved Juanda, has been stripped of his Dixie Mafia kingdom and is forced to do menial jobs for the Russians. The power dynamic shifts once again when Riva's sister, Zlata, arrives to change the game.
