After a dozen high-profile athletes from all over the world go missing, Lloyds of London hires an insurance detective by the name of "Mike Harbor" (Ross Hagen) to investigate--and if possible rescue--a particular jai alai player who is insured by them. In the course of the investigation he soon discovers a secret island belonging to a beautiful doctor named "Dr. Tsu" (Nancy Kwan) who commands a select team of females that kidnap certain athletes for the purpose of harvesting their organs. The problem for Mike is that Dr. Tsu is well aware of his investigation and she intends to stop him at all costs. Anyway, rather than disclose the rest of the movie and risk spoiling it for those who haven't seen it, I will just say that this low-budget film definitely showed its limitations. Although Ross Hagen, Nancy Kwan and Sid Haig (as "Gregorious") all performed adequately, the rest of the cast was clearly second-rate and it showed. Additionally, some of the fight scenes were just plain awful. As a matter of fact, the best thing about this movie was the presence of some attractive women which included Roberta Collins (as "Laura"), Maria De Aragon ("Linda") and the aforementioned Nancy Kwan. So while this movie had its good moments I have a little difficulty rating it higher than I have. Slightly below average.
