Undercover FBI agent Elena signs a multimillion‑dollar contract under duress to work as the personal nurse for the suspicious tycoon Preston while investigating a smuggling ring. Amid collar punishments in locked rooms and overwhelming sexual tension, the two sink into an abyss of tangled love and hatred. When Elena’s undercover identity is exposed and she even becomes pregnant with Preston’s child, the real mastermind—the FBI director—sets a trap, abducting her and causing her to miscarry. To save Elena, Preston takes a bullet to the shoulder and fakes his own death with a disfiguring injury in a warehouse explosion, silently guarding the love of his life from the shadows at the cost of his very existence.
