Doctor Joyce Barnhardt, a highly respected organ transplant researcher, is made aware of an accident victim's death and autopsy that reveals the patient had recently received numerous organ transplants that showed no sign of rejection. She begins a search for the answers to this seemingly impossible surgery. Her search leads her to Seattle, Washington where she meets and falls in love with an ex-marine, Rick Marks, who is following the patient's death for life insurance reasons.
Her quest for answers leads her to "Brothers Hospital" in Miami where she gains more insight into the medical procedures and suspects the hospital is involved in criminal activities. Ultimately, she is taken to a Bahamian Island, where she is imprisoned and forced to aid Dr. Sevorski in his procedures that "program" young kidnap victim's organs to be transplanted to the very rich and powerful patients at the Brothers Hospital. Doctor Sevorski refers to his research laboratory as "The Garden".
Finally, Rich Marks and law enforcement discover the entire criminal scheme that not only involves organ transplants but heroin smuggling. Dr. Barnhardt is rescued from the island, but mad Dr. Sevorski escapes to begin further work in South America.
