本片是著名影星彼得·乌斯蒂诺夫第六次扮演神探波洛，原著创作于1938年，与克里斯蒂的另外两部作品《阳光下的罪恶》、《加勒比海谋杀案》组成了别具风情的“海岛谋杀三部曲”，书中讲述一位女暴君被谋杀，而她的家人个个都有杀人嫌疑，最终大侦探波洛通过抽丝剥茧的缜密推理找出了真凶。值得一提的是亨弗莱·鲍嘉的妻子、好莱坞著名影星劳伦·巴考尔应邀在片中扮演了一位女富翁，对破案起到了关键作用。

　　Myron Breckinridge is waiting for his sex-change operation while a stoned surgeon stumbles into the operating room. Before the drugged doctor begins Myron's operation, he counsels him. Myron persists and the doctor goes through with it. An enthusiastic audience observing the operation applauds the medical achievement and rises in a standing ovation. After the operation, Myron arrives in Hollywood as Myra while in the rest of the film Myron pops up from time to time as Myra's alter ego. Myra goes to an acting academy owned by her uncle, Buck Loner, a former cowboy star. The real reason for Myra's arrival is to claim her half of Uncle Buck's estate, which she says she's entitled to. Buck Loner stalls by giving her a job teaching the history of motion pictures. Buck Loner has several friends. One of them is Letitia Van Allen, an ancient Hollywood talent scout. The sex-starved septuagenarian runs an acting agency "for leading men only."
