Callie Wallis is militantly self-reliant, but when her sister's mountain of medical bills threatens to avalanche, she does the unthinkable: She asks her boss, Adam, for a loan. A member of the famous Hughes clan, Adam is fed up with the scheming fortune hunters and paparazzi that dog his every step. When his trusted assistant, Callie, asks for money, he ups the ante to a marriage of convenience instead. Each plans to get what they want from the arrangement and leave, but when a black-market treasure hunter decides Adam has something he wants, can the pair escape both danger and love? And can Callie protect the secret she's kept from Adam for years?
