Ken, famously known as the “Invincible Hand,” had an extraordinary ability to identify mahjong tiles and playing cards by touch, earning him legendary status. After stepping down from his role as Chief Security Consultant in Las Vegas, he returned to his roots in Macau. There, he reunited with his old friend Benz, along with Benz’s son Cool and nephew Karl, both of whom aspired to learn from Ken. Ken challenged Cool, stating that if Cool could successfully deceive him or defeat him, he would take him on as a student. Meanwhile, Cool’s stepbrother Lionel, an undercover operative, had infiltrated an international gambling syndicate. This group aimed to collaborate with global illegal gambling rings to manipulate soccer match outcomes. Lionel secretly recorded their meeting, storing the incriminating evidence in a fake eye, which inadvertently ended up with Rainbow, Ken’s only daughter, putting her at risk. Consequently, the retired Ken was compelled to use his “Magic Hand” once more to thwart the sinister scheme.
