In 1993, reports emerge that North Korea is developing nuclear weapons. Former South Korean military officer Park Suk-Young is recruited by the National Intelligence Service (NIS) to infiltrate the highest ranks in North Korea and learn about their program. He is given the code name "Black Venus." Besides Park Suk-Young, only the South Korean President and NIS foreign affairs director Choi Hak-Sung are aware of Black Venus' existence.
Park Suk-Young then travels to Beijing, China under the guise of a salesman in an attempt to interest high ranking North Korean official Ri Myung-Un in a business deal. As time passes, he gains the trust of Ri Myung-Un and he is even given a chance to meet the North Korean leader Kim Jong-Il. But first, he must pass through Section Chief Jung Moo-Taek of the North Korea State Security Department.
During the run up to the 1998 South Korean presidential election, Park Suk-Young discovers secret deals between high-ranking South Korean and North Korean individuals. He becomes conflicted.
