Jack and Ella have come to Vegas to renew their wedding vows, with Ella’s surly younger brother, Matt, reluctantly in tow.
Stalking the neon-lit streets of Vegas, the vampires hide behind the façade of a successful cosmeceutical company that is about to announce its newest product; one that promises to change everything.
Determined to sample the delights of Sin City, Matt inadvertently entangles Jack and Ella in the vampires’ web. Ella is soon in the lead vampire’s sights.
Joined by a ragtag army whose numbers include a disgraced priest, a filmmaker, a DJ, and a professor of gothic literature who now lives within the tunnels that lie hidden beneath the desert city, Jack must face a showdown with the vampires to save his wife; to save humanity itself.
