After Nikky and Mark take refuge in an abandoned temple inhabited by numerous cats, Mark reveals he was a bank employee who handled the jewellery of the Countess of Fleet; he lost his job when he was attacked en route with jewels stolen from him. Mark assumes Stratos to be his attacker who hid the jewels somewhere in the Bay of Dolphins. The duo spend the night there and Stratos attempts to track them down, only to be scared away by the resident cats. The next morning, Nikky and Mark are discovered by a British gentleman named Anthony Gamble and are taken to his summer villa in Agios Nikolaos where his wife, Cynthia, looks after them. But it turns out Anthony is partners with Stratos, assuring Stratos that he will handle the interlopers so he can make the deal without trouble. Nikky later learns from the Gambles that a rich woman named Madam Habib is travelling Greece on her yacht, Mark realizing that Stratos intends to sell the jewels to her. But Mark is revealed to be drugged by Cynthia, with the couple making preparations to send him to Athens to receive medical care. On the way to the hospital, Mark wakes up and tells Nikky he has to stop Stratos before it is too late. Nikky attempts to stop Mark before he kisses her and leaves, deciding to reach Madame Habib's yacht as Mark fails to prevent Stratos from escaping with the jewels. She tells Madam Habib that Stratos is a thief and that the jewels she intends to buy from him were stolen from the Countess of Fleet, who happens to be an old friend of Habib's. Stratos shows up to sell the jewels, but so do Mark, Frances and Alexis. A fight ensues. In the end, Madam Habib has police take Stratos off the yacht, and returns the jewels to Mark. The final scene shows Alexis leaving by boat, waving at Mark and Nikky, and implying that they will soon get married by the time they return to Crete. The lead character is somewhat younger than in the novel. Traveling alone in the book, she is accompanied by her aunt in the film. The film is somewhat dark, similar to other Disney live-action features made in the 1950s and 1960s for more mainstream audiences such as "Treasure Island" (1950) and "20,000 Leagues Under the Sea" (1954). It was Walt Disney's penultimate live-action film in which he was credited as producer while alive.
