Australia has become a radioactive wasteland, leaving few areas with access to fresh water and agriculture, including the Green Place of Many Mothers. While two children, Furiosa and Valkyrie, are out picking peaches, their peaceful day is disrupted when raiders discover this oasis. In a daring attempt to protect their home, Furiosa tries to sabotage the raiders' motorcycles, but she is ultimately captured as a trophy for their ruthless leader, Dementus of the Biker Horde.
Furiosa's mother, Mary Jabassa, refuses to let her daughter be taken without a fight, pursuing the raiders to their camp, where she takes down almost all of them. However, the last raider delivers Furiosa to Dementus, who is about to learn the location of the Green Place. In a fierce struggle, Furiosa wields her strength, mortally wounding Dementus before he can divulge vital information.
Mary infiltrates the camp to rescue her daughter, but Dementus is relentless in his pursuit. Sacrificing herself to give Furiosa a chance to escape, Mary hands her daughter a peach pit as a keepsake, a powerful reminder of their bond. Before Furiosa can flee, she is forced to witness the brutal crucifixion of her mother. Stricken by grief and guilt, Dementus adopts Furiosa, hoping she will lead him to the Green Place.
Time passes, and Dementus launches an attack on the Citadel, a neighboring settlement abundant in water and food. However, the brutal War Boys, an army loyal to their warlord Immortan Joe, successfully repel his forces. Shifting tactics, Dementus employs a cunning Trojan Horse strategy to capture Gastown, an oil refinery that sustains the Citadel. In a treacherous negotiation, Joe recognizes Dementus's control over Gastown and allows an increase in supplies in exchange for Furiosa's freedom and assistance from the Horde’s physician. Fueled by her desperation to escape, Furiosa has a star chart tattooed on her arm, a roadmap leading her home.
Imprisoned with Joe's "wives" in a fortified vault, Furiosa contemplates her survival. When Dementus's son, Rictus, shows interest in her, she seizes the opportunity to execute her escape plan. In a gripping scene, Rictus attempts to overpower her, but Furiosa cunningly slips away using a disguise made from her own hair.
For over a decade, she masquerades as a mute boy, navigating the ranks of Joe's men. During this time, she participates in the construction of the War Rig, a fierce supply tanker designed to withstand the harsh conditions of the Wasteland. With a plan set to escape during a supply run, she waits for Joe to send his top driver, Praetorian Jack. However, their run is interrupted by the rogue lieutenant, The Octoboss, who launches a devastating air assault on the Rig.
Furiosa and Jack unite against their common enemy. When it appears she might take control from Jack during a carjacking attempt, he recognizes her fighting spirit and offers her a deal: assistance in rebuilding his crew in exchange for training her to escape. Their bond grows as they prepare for a bold move to liberate themselves, particularly when Joe decides to attack Gastown, which Dementus has allowed to deteriorate.
Dementus ambushes them during their mission, leading to a harrowing escape where Furiosa sustains a serious injury. Despite the pain of losing her arm to sever her chains, her indomitable spirit drives her forward. With relentless determination, she manages to return to the Citadel and formulates a strategic plan with the help of Joe's aide, The People Eater.
Through cunning tactics over a drawn-out conflict, Furiosa and the War Boys ultimately crush the Horde. Having lost her path, she makes a drastic decision to shave her head, fixating on her mission to vanquish Dementus. After a heated chase across the desert, she captures him and confines him at the Citadel, expressing her defiance by using his body as fertilizer to grow a peach tree from her mother’s seed. Elevated to the role of Imperator, Furiosa earns command over a new War Rig, and as she meets Joe’s group of five captive wives, she begins to forge a new chapter in her relentless quest for freedom and justice.
