1990: THE BRONX WARRIORS

Ann is the 17-year-old heiress to the arms manufacturing giant, the Manhattan Corporation. Unable to face her guilt over inheriting a morally questionable company when she turns 18, Ann runs away into the lawless wasteland of the New York City borough of the Bronx. The film's opening intertitle explains: "1990. The Bronx is officially declared 'No Man's Land'. The authorities give up all attempts to restore law and order. From then on, the area is ruled by the Riders."

Attacked by a roller skating gang called the Zombies, Ann is saved by members of a motorcycle gang called the Riders and taken under the protection of their leader, Trash. They quickly fall in love.

Another powerful gang, called the Tigers, kills a Rider named Chris. The Tigers’ leader, the Ogre, informs Trash that Chris was carrying a "gizmo" – a covert listening device that looks like a watch and works on the same radio frequency as the Manhattan police. The Manhattan Corporation uses it to confirm Ann's location.

The Manhattan Corporation hires Hammer, a ruthless and psychopathic mercenary, to retrieve Ann. When he enters the Bronx, he kills two Riders, plants a golden ring in the gang's headquarters, and then flees the scene. The Riders give chase and try to catch Hammer, but he escapes.

Ann finds the golden ring and gives it to Trash, who recognizes that it belongs to the Tigers. Believing the Tigers were behind Hammer's attack, the Riders call for war. Trash, however, is skeptical.

The Zombies ambush and kidnap Ann. Trash tells the other Riders that he wants to ally himself with the Ogre to rescue her. Most of the gang dislikes this idea. As Trash and two loyal Riders fight their way across the Bronx, they encounter a musical-theatre-inspired gang, and a subterranean-dwelling gang called the Scavengers, which kills one of the Riders.

Meanwhile, a traitorous Rider named Ice discovers a local man named Hot Dog is working with Hammer. Ice informs Hammer about Ann's kidnapping and Trash's plan to save her. Ice then goes to the Zombies' headquarters and warns their leader, Golem, about the impending rescue attempt.

Trash reaches the Tigers' headquarters, where Hammer attempts to frame him for killing a Tiger. When Trash is captured, however, he convinces the Ogre that the murderer is Hammer and he is working to turn all the Bronx gangs against each another. Trash further explains the situation and proposes that he and the Ogre save Ann. The Ogre agrees, and so he, his right-hand-woman Witch, and Trash head back across the Bronx.

The trio make it to the Zombies' headquarters. While the Ogre and Golem duel, Trash frees Ann from her chains. When Ice tries to run away, Hot Dog tries to stop him and is stabbed to death by Ice. The jaded Ice criticizes Trash for being an unrealistic leader and risking everything for a wealthy outsider like Ann. The two men fight until Ice is impaled and dies.

Ann celebrates her 18th birthday at the Tigers' headquarters. During the party, a Manhattan Corporation private army, led by Hammer, invades the building and proceeds to massacre everyone there. Despite his orders to retrieve Ann, the insane Hammer declares there will be no survivors. Ann is shot and killed while defending Trash from gunfire. Infuriated, Trash kills Hammer and drags the corpse behind his motorcycle as he rides through the Bronx.

Ann celebrates her 18th birthday at the Tigers' headquarters, after being freed from the Zombies' captivity, as the Manhattan Corporation’s machinations are exposed and rivals are confronted.

The ending sees Ann coming of age amidst chaos, her fate intertwined with the Bronx’s violent power struggles. The alliances and betrayals underscore how survival in this lawless world depends on choosing sides wisely, and the film closes with a nod to the ongoing cycle of conflict, leaving the Bronx's future as uncertain as ever.
