As a member of the CIA's elite Black Opals, Natalya Trubachev must live a lie, working undercover as the lover of Dmitri, a Russian mob boss. His business is trafficking vulnerable Las Vegas strippers overseas for twisted sex games. Natalya's business is to blow the ring wide open and bring down Dmitri and his American contacts. But the stakes are raised when she learns that the next target is her own sister Kate, a dancer in the famed club Fantasia. Only now does Natalya realize how personal her mission has become, and how far she's willing to go to complete it.

The manager of Fantasia is Brandon Moretti, an undercover detective who keeps a close eye on his girls, and an even closer one on his sinfully sensual newest hire. For Natalya, working the club could be the break she's been waiting for. But for Moretti, Natalya is a possible link to a killer. Only he never counted on her being so lethally seductive or so dangerous to get close to. As every forbidden pleasure between them is stripped away, his own secrets threaten their security, but it's Natalya's secrets that could destroy them both.
