On assignment in the Middle East, television journalist
Cotten Stone stumbles upon an archeological dig that
uncovers the world's most-sought-after religious relic:
the Holy Grail. With his last dying breath, Dr. Gabriel
Archer gives it to Cotten, uttering "You are the only one"
in a language she's heard from only one other person--her
deceased twin sister.
What begins as a hot news story for the ambitious young
reporter soon turns into a nightmare when the Holy Grail
is stolen and strange "accidents" befall her dearest
friends. Running for her life, she turns to John Tyler, a
priest with firsthand knowledge of religious artifacts,
for help. An anonymous source leads them to New Orleans
during Mardi Gras, where an abominable experiment is
underway that--unless destroyed--promises to unleash an
ancient evil upon the Earth.
