Kurt Nobel, known as "The Real Estate King," invites a mixture of odd guests to his mansion on the
Isle of Ease
for a week of snorkeling, scuba diving, deep-sea fishing,
and general fun in the sun. The occasion is to celebrate the millionaire's recent marriage to his new young wife, singer Barbie.
But all is not pure pleasure and merriment on the tropical island. One person plans an intriguing way to commit murder, and may get away with it, if not for the fortuitous eyewitness, eight-year-old Evie Frederique.
