Miraculous Love

Professor Fulton (Cary Grant) is a scientist who is researching a magical drug that can rejuvenate people. One day, the chimpanzee that Fulton used to test the drug escaped from the cage and "caused havoc" in the laboratory. Unexpectedly, he accidentally created the miracle drug that Fulton had always wanted to develop but had never succeeded. Fulton, who knew nothing about it, accidentally drank the drug. Soon, the drug took effect. Fulton behaved uncharacteristically like a twenty-year-old boy. Secretary Louise (played by Marilyn Monroe) comes to visit Professor Fulton, but unexpectedly she is invited by him to go swimming and skating. Afterwards, Fulton's wife Edward (Ginger Rogers) also took drugs by mistake, and a series of hilarious interesting stories unfolded.
