A scientist (Rock Hudson) experimenting on a human fetus discovers a method for accelerating its growth into a mature adult human (Barbara Carrera) within just a few days. Problem is, once she begins to age rapidly as a side-effect of the Scientist's experiment, she turns into a homicidal maniac as she desperately seeks to stop her aging. Interesting Sci-Fi thriller meets classic retelling of the Frankenstein myth, this film carried an all-star cast including Hudson, Diane Ladd, Roddy McDowall and Dr. Joyce Brothers (as herself). Ah, the misfortunes of experimenting with fetuses... Fun mid-seventies fantastic horror.
