Well respected Pompeiian Glaucus performs an act of kindness by buying
Nidia, a blind slave being mistreated by her owner. Nidia falls in love with
her
new master, but he only has eyes for Jone. Jone in turn is lusted after by
Arbace, an Egyptian high priest of Isis. When Nidia beseeches Isis for help
in
capturing Glaucus' heart, Arbace gives her a "love" potion, which really will
affect his mind and not his heart, thus opening the way to Jone for himself.
When Arbace's disciple is murdered Glaucus finds himself in hot water,
shortly after which Mt. Vesuvius erupts.
