The young and handsome "technician" Zhihe (Kim Woo-bin) is known as the strongest brain in the theft world. He can handle any vault and forge all information to formulate a watertight theft plan. He teamed up with the "controller" human resources deployment expert Jiuren (Go Chang-seok) and the "invisible" super hacker Jong-bae (Lee Hyun-woo). Each of the three is a top expert in the industry. They easily stole jewelry worth 3 billion under the noses of the police in 3 minutes and became famous overnight in the theft world. Hearing about the strength of the three, Mafia President Zhao (Kim Young-chul) decided to recruit them, hoping that they would join the most difficult theft mission - stealing 150 billion in cash in 40 minutes from the Incheon Customs, which has the highest security level in Asia. Can these three highly capable "technicians", "controllers" and "invisibles" successfully complete their mission? Or will they fail and fall into the law? And who will win the scheming struggle between Zhihe and President Zhao?
