The late Dr. Jekyll's daughter returns home to help out her guardian, who also happens to be a mad scientist (Carradine) searching for a formula for eternal youth. It seems the retina from the human eye is needed for this formula, many of which will be needed for his experiments. Soon a lost nephew turns up who has a habit of transforming into an apish creature from time to time, causing mucho fear and panic. A schlockfest for sure! Nice color with English Subtitles, from 16mm.
