Parliamentary secretary Toru Washizu (Tsuyoshi Kusanagi) has devoted 20 years of his life to Kosuke Inukai, a member of parliament and cabinet minister. Toru works behind the scenes as Inukai's "shadow," deftly handling the petitions of Inukai's supporters and crushing any hint of scandal. Cool and collected, Toru rarely betrays emotion and would humble himself to anyone to get what Inukai needs. But then a shocking event changes everything. Toru's only son, Taiki, is gravely injured in an accident that leaves him close to death. Toru is stricken with worry and fear for his son, but Inukai orders him to conduct a cover-up. Feeling betrayed, Toru, who once would have done anything for Inukai, begins to question everything.

But why did Nishina, a supposedly elite man, move into this shabby apartment, and why is he so kind to Fujiko...? It seems that Nishina, who does not speak much, is a stranger to Fujiko...?
