When Nikki Ferris and her aunt took a trip to a small Greek island, they never expected to get involved in jewel theft and murder. A strangely reluctant innkeeper, a handsome Englishmen, a missing boy and a mysterious yacht all play a part in this Mystery/Romance based on a Mary Stewart novel.
Vacationing in Crete with her Aunt Frances, a musicologist, 17-year-old Nikky Ferris learns that their reservations at the Moon-Spinners Hotel have not been recognized, but hostile owners Stratos and his sister, Sophia, reluctantly give them a room. They meet Mark Camford, a young British expatriate, artist, and skindiver, apparently having a running feud with Stratos. Because of her attraction to Mark, Nikky becomes involved when she finds him wounded in a deserted church where he crawled after being ambushed and shot by Lambis, Stratos' cohort, the night before. Her complicity uncovered, Nikky is imprisoned by Stratos in a windmill. After being rescued by Mark and Sophia's son, Alexis, Nikky learns from Mark that he was sacked from his job as a messenger for a London bank because of a jewel robbery he believes Stratos to have committed. The couple then encounter Anthony Gamble, a self-styled British consul who as Stratos' partner is planning to sell the jewels to Madame Habib, a millionairess. These revelations send Mark on a chase after Stratos, while Nikky appeals to Madame. Following a struggle, the police board Madame's yacht, apprehend Stratos, and thereby exonerate Mark.
