Dewu (Tae-hyun Cha) is a bookstore owner, and his good friend Young is obsessed with collecting all kinds of books and Western wonders all day long. The seemingly stupid Dewu is actually a knowledgeable and smart guy. His true identity is the son of the right prime minister of the dynasty. The political disputes caused by the interests of ice, which are more precious than gold, made the left prime minister dissatisfied, and he wanted to get rid of the right prime minister who was honest and loyal to the emperor who hindered his progress. The Zhao Group was eventually convicted of treason and bribery, causing the tragic death of the right prime minister and Young, and Dongxiu (Ji-ho Oh) was also implicated for being honest and upright in supervising the ice bank. After lurking for three years, Dewu came up with a plan to uproot the Zhao Mingxiu gang. He persuaded Dongxiu and his sister Xiulian (played by Min Xiaolin Hyo-rin Min) to join his ice-stealing plan, and combined a series of masters of private finance, disguise, explosives, transportation, diving, intelligence and other aspects to form a team and carried out this crazy action step by step... The film was nominated for the 33rd Blue Dragon Award for Korean Film in 2012 and was called the Joseon version of "Ocean's Eleven".
