Reiji Mikoshiba, an undefeated lawyer who always wins a suspended sentence no matter what the charges are, has been shunned by the people around him because the rewards he raises from his clients are exorbitant and notorious.

It is said that Mitsuko Tojo, the wife of the owner of the town factory, turned off the respirator of her husband in the hospital and killed him because he wanted insurance money.
