Ryutaro Ogami (Min Tanaka) is a man behind the scenes of the country, and sometimes helps politicians and business leaders to cover up various scandals and sensational events. However, Ryutaro's son Ryu Ogami (Mackenyu Nitta) is the opposite of his father, insisting on the concept and behavior of justice. However, he faces the most difficult challenge in his life - the son of the next prime minister candidate who is close to the Ogami family dies mysteriously. Ryutaro is from the dark side of the country, and Ryu is from the light side, gradually approaching the prototype of the great evil hidden in the political world.
