Jin Sun Mi (Oh Yeon-seo) is a successful real estate CEO who has the ability to exorcise demons from bad-luck properties. But to the demons living on Earth, she is known as Sam Jang, who carries the irresistible scent of a lotus flower and can give great powers to anyone who eats her. When Sun Mi was a young girl, Son Oh Gong (Lee Seung-gi), a trouble-making deity, tricked her into releasing him from a castle where he was imprisoned and made a contract with her to always appear and protect her whenever she called out his name. But he tricked her again by removing her memory of his name. In modern times, Son Oh Gong freeloads off of Woo Hwi (Cha Seung-won), another deity known as Woo Ma Wang who works as the CEO of an entertainment company and enjoys more fame and adoration than some of the celebrities in his company.
Son Oh Gong is intent on finding Sam Jang so that he can eat her and become the most powerful god. His friend, top idol star P.K (Lee Hong–gi), wants just a nibble for himself. When Song Oh Gong realizes that Sam Jang is Sun Mi, he at first protects her from attacks from other demons to save her for himself. But with the help of Woo Ma Wang, will Sun Mi find a way to force Son Oh Gong to serve as her protector?
