The drama tells the story of Kim Joowon, an arrogant and eccentric CEO who maintains the image of seeming perfection, and Gil Raim, a poor and humble stuntwoman whose beauty and body are the object of envy amongst top actresses. Their accidental meeting, when Joowon mistakes Raim for actress Park Chaerin, marks the beginning of a tense, bickering relationship, through which Joowon tries to hide a growing attraction to Raim that both confuses and disturbs him. To complicate matters further, a strange sequence of events results in them swapping bodies.
