A friend of the Chief's is an obvious suspect in the murder of her husband, but the Chief believes that the evidence against her is too obvious. He soon proves her innocence, but is she really the victim of a frame-up, or is it all rather more complicated than that?

The son of an old friend, fearing that his father's life is in danger, asks the Chief to go to Tokyo. Once there Ironside finds his old friend wheelchair-bound as a result of an accident, and begins to work on his own theory about who might have hired a hitman to kill such a respected old man.
