Fati, recently married to Arch Lindor, a charming but mysterious man she met on a trip to Spain after resigning from the Los Angeles Police Department, learns that she has inherited ‘Florestal’, her Mexican-born, murdered great aunt’s sprawling estate in San Marino, California. Forced to travel alone to the west coast from the home in Florida she shares with her new husband because of his business commitments, Fati finds herself increasingly dependent on her elderly great aunt’s former ‘walker’ (escort), Walter Mulday, who is only too willing to aid her in vital decisions pertaining to the settlement of the deceased relative’s legally contested fortune, which includes many priceless pre-Columbian Mexican art works, an area in which he claims to be an expert. As Walter forces himself into her life against her wishes and other wealthy, elderly women with whom he has been associated are subsequently murdered, Fati pleads with Arch to abandon his business obligations in Florida and join her in California. However, when Arch arrives, Fati is dismayed to discover that Walter is as equally adept at deceiving and manipulating him as he is with her, although employing entirely different means. She quickly realizes that if Walter has selected her as a future victim, which she strongly suspects, she will be forced to rely on her police training and herself alone.
