While working a graveyard shift on Valentine's night, emergency room nurse Lydia Hale saves the life of a heavily wounded gunshot victim, only to discover she has treated Soren Moretti, the feared kingpin of the city's mafia underworld. Because she looked directly upon his face during surgery, Soren refuses to let her return to civilian life, issuing a terrifying ultimatum: sign a thirty-day marriage contract to live under his armed protection, or be silenced by rival cartels seeking his blood. Reluctantly stepping into Soren's heavily fortified penthouse, Lydia finds her stubborn moral defiance clashing with Soren's dark possessiveness. As rival syndicate assassins stage violent assaults on their estate, Soren repeatedly risks his life to protect Lydia, causing passion to erupt between them. With the thirty-day contract nearing its expiration, will Lydia choose her hard-won civilian freedom, or remain at the side of the mafia king?
