His employer, **Mr. Oliver Oxley** (Charles Coburn), is eager for the breakthrough, hoping it will lead to commercial success. However, things take an unexpected turn when a chimpanzee in the lab accidentally mixes chemicals, inadvertently creating a working rejuvenation serum.

Unaware of the chimp’s involvement, Dr. Fulton drinks the serum himself and regresses to a youthful, carefree state, behaving like a teenager. His newfound youthful energy causes a series of comedic mishaps, including flirting with **Lois Laurel** (Marilyn Monroe), Mr. Oxley’s stunning and naive secretary. Soon, other characters, including Dr. Fulton’s wife, **Edwina** (Ginger Rogers), also ingest the formula, leading to increasingly outlandish and hilarious situations as they all experience temporary youth.

Monroe’s performance as Lois is full of light-hearted fun, and while the character is written primarily for comedic relief and glamour, Monroe manages to elevate the role with her natural charisma and charm. The role helped solidify Monroe’s status as a talented comedic actress, further contributing to her growing fame in the early 1950s.
