Every six years in the last two millennia, an ancient order of superhuman martial artists called Jiu Jitsu faces a vicious race of alien invaders in a battle for Earth. The invaders have always lost to Earth's defenders, up until now.
In the jungles of Burma, a tense chase unfolds as American soldier Jake Barnes—Alain Moussi—fights for his life against alien shuriken and the rumble of unseen foes. He is saved by a mysterious Western man and handed over to two Burmese fishermen, who, after a confusing language barrier and a moment of foreboding, take him to a nearby military post. Jake awakens with amnesia, unable to recall the events that brought him to this point, and the story unfolds through a haze of questions rather than clear answers. An intelligence officer named Myra—Marie Avgeropoulos—presents the case to a cautious command, trying to reconcile villagers’ talk of a comet appearing every six years with a temple portal that seems to govern the invasion.
Into this fragile equilibrium storms Keung—Tony Jaa—an advanced Jiu Jitsu fighter who cuts through the base with ruthless efficiency to rescue Jake. The two escape through a long, brutal sequence that reveals Jake’s own prowess with the martial art, hinting at a shared history with the fighters who guard Earth. They are soon reunited with a team led by Harrigan—Frank Grillo—a seasoned mentor who commands a small chorus of Jiu Jitsu masters. The group has a memory of Jake that he cannot access, and yet their trust in him is unshakable as they navigate a world where humans and aliens collide in the same arena.
As the unit moves through jungle and ruin, a brutal attack from Brax—Ryan Tarran—the invader’s ruthless leader, strips away any sense of safety. Jake and his companions are forced to improvise, and they are driven back toward a hidden nexus: a cave where the mysterious savior once resided, now revealed to be Wylie—Nicolas Cage—a once-maverick Jiu Jitsu veteran who carries the weight of past battles on his shoulders. Wylie and the rest of the fighters reveal the existence of a temple that houses a portal used by the invaders to slip into Earth’s realm. The revelation reframes Jake’s amnesia as part of a larger, longer conflict and redefines his purpose within the fight.
Within that cave, the truth about Jake’s past starts to surface. Brax’s assault tests the group to its limit, and the battlefield grows personal: Carmen—Juju Chan—a former lover of Jake, survived the earlier clashes and becomes a key ally as the battle intensifies. Wylie reveals a difficult truth: he is Jake’s father, a confession that carries heavy shame but also a path toward reconciliation and renewed resolve. The revelation shifts the stakes from mere survival to reckoning with a legacy that Jake never consciously embraced.
The human survivors rally with the Jiu Jitsu fighters, and a new plan forms: Jake must confront Brax head-on, using every trick learned on the mat and every memory he slowly recovers to turn the tide. The fight returns to the temple and its perilous portal, where the invaders’ power hinges on the same doorway that has defined the conflict for centuries. Wylie makes a final stand, sacrificing himself in a fierce duel to buy Jake time, while Captain Sand—Rick Yune—and the remaining soldiers provide critical support from the outskirts, a reminder that Earth’s defense rests on collaboration between the martial artists and the wider human forces.
With Brax looming as the ultimate nemesis, Jake discovers a vulnerability he had previously overlooked: fire. Seizing the opportunity from a hard-won earlier confrontation, he wields this weakness to devastating effect. In a long, grueling final sequence, Jake is pushed to the brink, his body battered yet unbroken, until he corners Brax near the portal. A grenade is driven into Brax’s core, and in a explosive, cathartic moment, the enemy is hurled toward the gateway and into the realm he had hoped to conquer. The portal seals behind him, and Earth’s defenders, both human and Jiu Jitsu, stand battered but victorious, ready to rebuild and remember the cost of the battle they just endured.
In the aftermath, the survivors gather amid the jungle’s remnants and the temple’s quiet depths. Jake’s amnesia is replaced not by a full recall of every moment but by a renewed sense of self and purpose, forged in the crucible of memory, loyalty, and love. The story closes on a note of hard-earned peace, a fragile truce that rests on the shoulders of those who continue to train, fight, and protect a world that has faced down an ancient, relentless threat.
