Dwight "The General" Manfredi is the American Mafia capo from New York City who has just finished serving a 25-year prison sentence. Upon release, Dwight's boss sends him to Tulsa, Oklahoma, to establish criminal operations there.

In season two, Dwight and his crew continue to build up and defend their growing empire in Tulsa but, just as they get their bearings, they realize that they're not the only ones who want to stake their claim. With looming threats from the Kansas City mob and a very powerful local businessman, Dwight struggles to keep his family and crew safe while keeping track of all his affairs. Plus, he still has unfinished business back in New York.

In season three, as Dwight's empire expands, so do his enemies and the risks to his crew. Now, he faces his most dangerous adversaries in Tulsa yet: the Dunmires, a powerful old-money family that doesn't play by old-world rules, forcing Dwight to fight for everything he's built and protect his family.

In season four, Dwight fights to legitimize his empire and protect his crew as corrupt politicians, dangerous new enemies, and a crushing personal loss hit from every direction. However, every hard-won gain comes with even harder truths: about loyalty, leadership and the cost of ambition. Each move drags Dwight deeper into the street instincts he left behind in New York - turning Tulsa into a battleground and Dwight into the one threat no one can afford to underestimate.
