Detective Nishi has just lost his infant daughter and is about to lose his wife to a fatal illness. He is advised by the doctors to take her home so she can die in peace. Nishi also finds out his partner Horibe has been seriously wounded and may be confined to a wheelchair. Nishi visits Horibe who says that he would like to take up painting but cannot afford the hobby. Nishi borrows money from the yakuza to supply his friend with paint and to support a young policeman's widow whose husband was killed during an arrest. Haunted by the death surrounding him, Nishi carries out a plan to right the wrongs in his life. Having quit the police force, Nishi buys an old taxi, repaints it to resemble a police cruiser, and then single-handedly robs a bank. He promptly uses the money to repay the yakuza and to take his dying wife on a trip that will give her a taste of happiness.
