The plot of the series is based on the Byrd family, which consists of Martin, its head, his wife Wendy and their children, Charlotte and Jonah. Martin, as a financial consultant, helps a powerful drug cartel deal with illegal financial fraud. But one day Bird's partner informs him that he stole mafia money, so Bird has no choice but to promise the head of the drug cartel that he will return the stolen money and also earn several times more. To do this, the consultant's family moves from Chicago to the resort of the Ozarks, where they begin building a casino. Marty's new venture very soon begins to make a profit, but the FBI appears on the horizon of the family, and the bosses of the businessman demand even more revenue from Byrd.
