As business flags, tensions rise between Pete's grandparents, Otto and Audrey. Marius proposes a risky play to help Julia manage a dangerous client, but when they encounter problems, the "cousins" must rely on Audrey's expertise. While evading a mysterious pursuer, Marius visits former partners Katie and Karolina in NYC and remembers how three years ago, he made a powerful enemy of Vince.

Marius' exacting parole officer insists that he come into the city for a mandatory appointment. To get there on time, Marius must fend off Pete's curious cousins Julia, Taylor, and Carly, an increasingly suspicious Audrey, and a terrifying ambush. Meanwhile, Eddie becomes desperate in captivity, Vince's lieutenant Winslow hunts for Marius, and a reluctant Katie helps Marius cover his tracks.

Lured by the promise of a big payday in the bail bonds office's safe, Marius tries to work the angles with Pete's family. However, he finds it more difficult than he expected to manipulate Taylor, who harbors both a vicious temper and a dangerous secret of his own. Back in the city, Vince struggles with a difficult client at the poker table and takes his frustrations out on his crew.

Audrey and Otto argue over Audrey's unilateral decisions, the fallout from which may cost them their business. In the process of helping Otto investigate one of his nagging suspicions, Marius makes a major discovery about Audrey's finances. Meanwhile, Carly quizzes her mysterious cousin about his past, Julia rekindles her relationship with her ex Lance, and Vince has a new job for Eddie.

As they struggle to save the family business, Audrey strategizes with Marius, while Otto insists on doing things his way. Confronted by Carly's discoveries, Marius pays visits to both his old mentor and his former cellmate to backstop his identity as Pete. Taylor gathers evidence about the incident that left him suspended from the force, and Winslow follows Marius' trail to Katie and her family.

After discovering that Audrey risked BBB's future on a fraudulent investment, Marius convinces her, a reluctant Julia, and a team of his old compatriots to con back the money from the person who ripped her off. Unbeknownst to Audrey and Marius, Otto unilaterally enacts a perilous plan to save the business. Meanwhile, Katie and Brendon hold a NYC detective bound and gagged in their basement.

With all of the pieces in place, Marius sits down at Vince's poker table to make his final moves. Everything is going according to plan, until Vince becomes suspicious that he's seen this play before. When Audrey finds herself at the scene of a bloody crime, she must go against her instincts and trust her family to help her manage the situation. Julia embarks on a dangerous quest to save Lance.

After Marius' "Roosevelt Buffalo" plan works too well, the heist's fate is left in Pete's hands. Carly and Audrey investigate Marius and Maggie's motives for returning to the family. Julia enlists the aid of Otto, Sam, and - much to her chagrin - Lance in protecting Valerie from Colin. Taylor takes the final steps to frame the hitman for Winslow's death, and hopefully save Audrey.
