Emma, the eldest daughter of a chaebol who hides her identity, is mistaken — because she flies economy — by the family of her future sister-in-law Sarah for a "pregnant mistress scheming for the inheritance," and is subjected to deadly persecution. From a forced plane landing to having her baby snatched at the hospital and her family heirloom crushed underfoot, Emma fights to the death to protect her child in dire straits. In the end, her billionaire chaebol brother Arthur descends like a divine army and sees through the vicious true faces of his fiancée's family. Once the truth comes out, the villains are fully blacklisted and thrown into prison, and Emma reclaims the dignity and happy life that belong to her.
