As Anthony Fait embarks on a daring heist alongside his team of thieves, their mission to steal precious diamonds for the mysterious Christophe leads them into an intense game of cat-and-mouse with Taiwanese intelligence agent Su. Their fateful encounter starts when Su intercepts Fait's initial dealings with Christophe, igniting a series of thrilling confrontations between the skilled thief and the resourceful agent.
As the crew accumulates a stash of glittering diamonds, including a rare bag of black gems, Su seizes her opportunity to warn Fait about the impending police pursuit. However, Fait's impulsiveness takes the lead, causing him to dismiss Su's urgent warning. Amidst an audacious attempt to escape past a heavily armed SWAT blockade, only Fait, Daria, and Tommy manage to slip away unscathed. Meanwhile, Su captures Miles, managing to recover a portion of the stolen diamonds, but to her disappointment, the precious black gems are still unaccounted for.
In the meantime, Fait's friend Archie discreetly inspects the black diamonds, while Christophe's enigmatic employer Ling learns from his assistant Sona that Christophe has suffered a violent attack, and Fait’s crew has made off with the valuable stones. That very night, an unexpected meeting between Fait and Su paves the way for a dramatic showdown. When Ling pressures Fait to return the black diamonds, he adamantly refuses, only to find himself ambushed by Ling's henchmen. Fortunately, with Su's timely intervention, Fait narrowly escapes.
As their investigation deepens, Archie reveals to Fait that rival gangsters are on the hunt for the black diamonds at Fait's workshop. After some soul-searching, Archie admits that he has caved to their demands, putting his safety on the line. The situation takes a darker turn when Ling calls Fait, holding his daughter Vanessa hostage in order to retrieve the valuable gems. Now united in their mission, Fait and Su must work together to not only reclaim the stolen diamonds but also rescue Vanessa, raising the stakes to an all-time high as they venture into Ling's treacherous world.
Fait's pursuit leads him to the incarcerated crime lord "Jump" Chambers, where he hopes to gain insights into Archie's robbery. However, Chambers is uncooperative, compelling Fait to infiltrate his nightclub in search of the diamonds. Unfortunately, this expedition yields nothing but frustration.
While this unfolds, Su and Archie undertake a risky journey to an underground club, intent on tracing the gangsters responsible for Archie’s assault. Faced with the club's strict no-guest policy, Su reluctantly steps into the club's brutal fighting ring to prove herself. Amidst the fierce matches, Archie spots their target, identifying him by his distinctive ring. This revelation leads them closer to uncovering that the diamonds are hidden within Chambers' bubble bath.
On their way back to the nightclub to retrieve the stolen gems, Su and Archie encounter yet another obstacle: Ling’s men, who have already made off with the diamonds. Meanwhile, Vanessa, bound with duct tape, cleverly manages to free herself and obtain a cell phone to contact her father. In a race against her phone's dwindling battery, she provides crucial clues about her location: an airport hangar.
With the clock ticking, Fait and Su quickly deduce that Vanessa is caught in a high-stakes operation orchestrated by Ling and spring into action. They realize that the upcoming auction features not only the stolen diamonds but also weapons of mass destruction. A careful examination of flight schedules pinpoints their target: a bustling airport set for multiple private landings that evening.
Arriving just in time, Fait and Su plunge into the chaos to rescue Vanessa and thwart Ling’s evil plans. They find themselves in a fierce confrontation, where Fait's crew battles Ling’s operatives while Su faces her nemesis in a dramatic face-off. In the midst of the turmoil, Su ultimately triumphs, forcing Ling to swallow a synthetic plutonium capsule before dismantling the device lodged in his neck.
With the authorities closing in, Fait makes a solemn vow to abandon his life of crime and begin anew, this time alongside Vanessa.
