Bloody Vow depicts a fatal arranged marriage between Vivian, the illegitimate daughter of an Irish gangster, and Damian, heir to an Italian mafia family. A MIT graduate, Vivian is used by her father as a political bargaining chip to wed Damian. During their engagement ceremony, she steals a biotech chip implanted inside his body, unaware that she has walked straight into a far bigger trap.
House arrest, smoldering sexual tension, surveillance and betrayal unfold layer by layer at the Long Island manor, where the two brilliant masterminds hunt each other as mutual prey. As her ex-boyfriend, an undercover FBI agent, Damian’s violent half-brother, and his mother—who has been imprisoned for twenty years feigning insanity—step onto the scene one after another, Vivian is forced to choose between survival, revenge, and an irresistible deadly attraction. This is never a marriage; it is a power game written in blood.
