This film begins with a biochemist named "Dr. Dan Scott" (Jack Kelly) feverishly working on a research project involving human adaptation to disease by using fruit flies. Although his experiments on various animals were a tremendous success he now wants to try it on an injured or sick human being. But complicating matters is the fact that his main sponsor, "Dr. Richard Bach" (Albert Dekker) vehemently disagrees with human research without further testing. He changes his mind, however, when he meets a patient named "Kyra Zelas" (Mari Blanchard) who is suffering from terminal tuberculosis and doesn't have long to live. To everyone's surprise, upon injecting the experimental formula, she fully recovers within hours. Unfortunately, both doctors soon learn that the serum has side effects they never reckoned with. Now rather than reveal any more I will just say that this was a fairly decent horror film which definitely benefited from the complete disdain Kyra had for any and all social norms that most people have to observe. She was totally without conscience and human feeling. Even so this movie was clearly a grade-B film and for that reason I have rated it accordingly. Average.
