 Mitchell Campion (Patrick O Neal) visits an out of the way island off the coast of Spain to recuperate after a month in the hospital from a serious auto accident. People on the island greet him as someone who visited there three weeks previously, although Campion has never been out of the United States. Incredibly, he recognizes a beautiful woman, Francesca (Lilyan Chauvin), whom he loves. An old man, Alexis Paninian (Anatol Winogradoff), provides a clue to the mystery.
