On the streets of downtown South Korea, there is a reticent and submissive man, Chi Dong-chul (played by Ggong). He works as a driving agent and is used to seeing the contempt and insults of others. The real him is a former member of the special forces who escaped from North Korea, willing to abandon everything in order to track down the murderer of his wife and children. In North Korea, he was respected by President Park, who knew that the president was killed one night, and the old man gave his glasses to Dong-chul before he died. Dong Zhe, who became an important suspect in this case, was involved in a series of whirlpools full of killings and conspiracies, not to mention the great secret hidden in that pair of glasses. North Korea's secret department is ready to move, and Senior Colonel Min se-hoon, the training instructor of the Air Force Special Force CCT (Park Xishun), is also in hot pursuit of Dong-chul. Standing in the forefront of the wind and waves, Dong Zhe was forced to deal with all kinds of forces on his own.
