Ozark Season 3 Episode 10, titled All In, changes the Byrdes’ lives forever and sets the tone for what comes next. The episode begins with Wendy spiraling after Ben’s death, drinking vodka in her car as she struggles with guilt. Marty retrieves Ben’s body from Nelson, cremates it, and lies to Ruth by saying Ben exposed them to Helen.

Ruth, devastated and suspicious, confronts both Marty and Wendy before walking away from the Byrde operation. Meanwhile, Helen confronts Navarro, positioning herself as the one who should control Byrde Enterprises, while also applying for her own casino license.

This prompts Wendy and Marty to scramble for a way to prove their value, eventually giving Maya evidence against the Lagunas cartel and suggesting the FBI could step in. Jonah discovers the truth about his uncle’s death and almost kills Helen himself.

By the end of Ozark Season 3, Episode 10, Wendy and Marty travel to Mexico with Helen, unaware of Navarro’s final decision. In a shocking twist, Helen is executed upon arrival, and Navarro welcomes the Byrdes, declaring it a new beginning. The finale ends with bloodshed, betrayal, and a clear indication that Marty and Wendy are now directly connected to Navarro himself.

The central focus of Ozark Season 3 Episode 10 lies in the Byrdes’ desperate effort to prove their worth to Navarro while surviving Helen’s maneuvering. Helen spends much of the episode tightening her grip, moving to secure a casino license of her own, and presenting herself as the safer, more reliable option.

This forces Wendy and Marty to think bigger than simple laundering. They decide their only chance is to end Navarro’s war with the Lagunas cartel by leveraging U.S. involvement.

In Ozark Season 3 Episode 10, Wendy suggests that if evidence shows the Lagunas operating on American soil, the government could justify military action. Jonah provides drone footage proving their presence, while Marty directly hands laundering records to Maya. It’s a risky move, but it gives the Byrdes leverage when they need it most.

While these strategic plays unfold, Ruth’s story takes a decisive turn. Unable to forgive Wendy for Ben’s death and disgusted by ongoing lies, Ruth cuts ties with the Byrdes. Her departure paves the way for Darlene, who shoots Frank Jr. in retaliation for Ruth’s assault and immediately recruits Ruth to help build her heroin business with Wyatt. This marks a significant realignment of loyalties in the Ozarks, shifting local power away from the Byrdes.

Jonah’s anger heightens the family conflict. After learning the truth from Helen, he almost kills her with a shotgun before turning his rage against the house, firing a shot through a window. His disillusionment shows how broken the Byrde family has become, even as Marty and Wendy are forced to act united to Navarro.

The climax delivers the brutal answer to the season’s central question: who does Navarro trust more, Helen or the Byrdes? By luring them all to Mexico under the guise of his son’s baptism, Navarro makes his choice. Helen is executed the moment she arrives, leaving Wendy and Marty standing in shock with blood on their faces.

In Ozark Season 3 Episode 10, Navarro embraces them, calling it a new beginning. The moment confirms that, despite their fractured family, strained marriage, and broken alliances, the Byrdes have secured a direct place under the cartel leader. This ending makes it clear that survival now means being “all in” with Navarro, no matter the cost.
