Titanic 2000 (1999)

"A Vampire's Lust is Unsinkable."

The luxury liner Titanic 2000 has set sail on its maiden voyage, and one of the passengers is the vampire Vladamina. Vladamina is searching for a woman she can turn into a vampire queen, and frustrated rock groupie Shari looks to be a perfect target. As various people get seduced and/or killed as the liner continues on its doomed voyage, Shari must chose between eternity as a living dead sex slave or a frigid grave at the bottom of the ocean.
