A tomboyish postulant at an Austrian abbey becomes a governess in the home of a widowed naval captain with seven children, and brings a new love of life and music into the home.

David, a college student, is looking for a job. He is hired by Dr. Stoner as a lab assistant for his research and experiments on snakes. David also begins to fall for Stoner’s young daughter, Kristina. However, the good doctor has secretly brewed up a serum that can transform any man into a King Cobra snake-and he plans to use it on David.
