[1][2] After losing everything, Hyun-soo (Park Yong-ha) spends five years glued to the computer screen as an unshaven, full-time "ant" (individual investor).

He ignites the fury of Hwang Jong-gu (Park Hee-soon), a gangster-turned-financier bidding for entry into the top percentile of the rich and powerful.

A fresh mobster persona, Hwang feigns elegance in his initialized Italian shoes, only to resort to kicking people for dramatic effect.

Hyun-soo joins the other members of Hwang's dream team for the 60 billion won heist: Jo Min-hyeong, an elite stock broker who doubles as the think tank of fraudulent trades (musical star Kim Mu-yeol makes his big screen debut); sexy private banker Yoo Seo-yeon (Kim Min-jung); Park Chang-joo, a second-generation chaebol CEO facing a management crisis (veteran supporting actor Jo Deok-hyun); and Bryan Choi (Kim Jun-seong), a Korean-American fund manager who fakes foreign investment as a "black-haired foreigner."

They have a famous broadcaster hype public attention while Bryan creates the illusion of foreign investment, and the cash starts flowing in from blind "ants."
