Daisuke Kami is the chief private secretary of a powerful parliamentarian, Yuji Tojo. He dreams of becoming a politician and changing Japan. Daisuke looks up to Tojo as his ideal of a clean politician. He wants to become just like him. Daisuke is very busy and barely has any time to spend with his wife Kumiko and daughter Chiemi. Despite this, Kumiko is very supportive of Daisuke.

One day Daisuke receives an urgent call from fellow private secretary, Ryoko Enomoto to meet with him. She shows him a memo with his signature on it. It says that Daisuke accepted a payment of 50 million from a construction company. He has no recollection of this, but Tojo abandons him telling an astonished Daisuke he has done a terrible thing. Tojo accuses Daisuke of trying to fit him for accepting a bribe. Daisuke is alone and an intense pursuit by the police and media begins.
