The stellar main cast returns with Jason Bateman, Laura Linney, Julia Garner, Lisa Emery, Sofia Hublitz, Skylar Gaertner and Felix Solis all reprising their roles.

There are some new additions to the cast including Bruce Davison as retired Illinois senator Randall Schafer, Alfonso Herrera as Javi, a member of the Navarro cartel, Veronica Falcon as Omar Navarro's sister Camila and Ali Stroker as Charles-Ann.

There are also cast members who will not be returning because their characters died in the previous season, including Janet McTeer as cartel lawyer Helen Pierce, Tom Pelphrey as Wendy’s brother Ben and Marylouise Burke as therapist Sue Shelby.

What is 'Ozark' about?

The Netflix Original tells the story of Marty Byrde (Bateman), a talented financial adviser who gets roped into laundering money for a Mexican drug cartel. He drags his wife, Wendy (Linney), and their two children, Charlotte (Hublitz) and Jonah (Gaertner), from Chicago to the Ozarks in Missouri, where they open a casino.

Season four picks up right where season three finished, with Marty and Wendy witnessing Pierce getting shot and killed at the hands of Navarro. However, that isn't the only problem they have: the couple are now even more tied to the cartel boss and Marty's right-hand woman Ruth Langmore (Garner) has turned against them and is now working for Darlene Snell.

In January, Netflix released its first trailer, giving a glimpse into what season four will touch on, including Jonah turning to money laundering himself.
