On Long Island, New York, the Costello mafia family rules with an iron fist. Ten years ago, Vivian's father—an accountant—was silenced after uncovering the family's money-laundering secrets. Now disguised under a new name, she infiltrates the heart of her enemies' territory as a casino dealer. Her plan is ingenious and lethal: she gets herself "captured" on purpose, turns down the cash to become the young heir's companion instead, seduces the Godfather with a song at the dinner banquet, then deliberately walks past him toward his son, igniting a rift between father and son. She plays both the genteel Godfather Vincent and the ruthless, sinister young heir Marco, determined to make this father and son pay for the blood debt. But Marco's obsessive possessiveness goes far beyond her expectations, and Vincent has fallen for her in earnest. The game of revenge begins to spiral out of control. When the gun barrel presses against her temple, Vivian must make her final choice between blood-debt and true love.
