A man dies in a car crash, but awakes with the spirit on another person. He becomes the head of two families and he agonizes over his two different wives.

Internal strife ensues for two decades as three family members vie for control over a large South Korean conglomerate.

The drama is about ambitious people clamoring to claim more power and success for themselves: an ambitious woman, a man born in a wealthy family and another woman who wants to escape from her poor background.
