Ella Somers, a gifted jewellery designer, is the illegitimate daughter of Swiss aristocrat de Villiers. As a child, her birth mother entrusted her to the fallen, bankrupt Somers family. She has long been treated by her mother and younger sister Ivy as a tool to gain wealth. Christian Winston, the icy tycoon ruling a vast business empire, suffers deep trauma from betrayal. In his childhood, his mother and stepfather Malcolm plotted to kill his father and seize the family fortune, leaving him unable to trust anyone. Bound together by a misplaced wedding, they sign a one-year contractual marriage. While fighting villains, uncovering their family secrets and healing inner wounds, the pair gradually fall in genuine love beyond their transactional partnership.
