Ozark is an American crime drama streaming television series created by Bill Dubuque and Mark Williams that premiered on Netflix on July 21, 2017. The series follows Marty Byrde (Jason Bateman), a financial advisor from Chicago who, after a money-laundering scheme with a Mexican drug cartel goes catastrophically wrong, is forced to relocate his family to the Lake of the Ozarks region of Missouri. There, along with his wife Wendy (Laura Linney), he must launder millions of dollars to pay off a dangerous cartel boss and keep his family alive.

What begins as a survival story quickly evolves into something far more complex: a layered examination of how ordinary people transform under extreme pressure, how power corrupts, and how far a person will go to protect the people they love — even when those people are complicit in their own destruction. Jason Bateman's performance is a revelation, marking a dramatic pivot from his long career in comedy; his Marty Byrde is a man who processes catastrophic stress with terrifying rationality, burying his panic beneath spreadsheets and contingency plans. Laura Linney matches him scene for scene as Wendy, a woman who discovers she may be more ruthless than her husband, and Julia Garner is simply extraordinary as Ruth Langmore, a sharp-tongued local criminal who becomes the show's moral lightning rod.

Ozark ran for four seasons, with the final season split into two parts, concluding in April 2022. The series received widespread critical acclaim, earned dozens of Emmy nominations, and established itself as one of Netflix's flagship prestige dramas. The show's distinctive blue-grey visual palette, the moral ambiguity of its central family, and its refusal to offer easy redemption made it one of the defining crime dramas of its era.
