Minneapolis DEA agent John Lawlor (Luke Evans) goes undercover to gather evidence of drug trafficking by billionaire Kwang (Sung Kang), head of a Taiwanese company, Kwang Enterprises. Due to a mishap which blows his cover, his supervisor forces him off the case. Meanwhile, his Taipei connection informs him about a ledger of Kwang. Although the department takes no notice of the tip-off, Lawlor takes off to Taipei regardless.
