Williams (in her first nonswimming role) is cast as a high school instructor who receives obscene notes from an unidentified student while becoming friends with student Saxon (Universal's attempt at finding a new James Dean). It turns out that Saxon is really a deranged goon and is
responsible for sending the notes. His problem is blamed on an equally demented father who lost control when his wife left him. Police lieutenant Nader helps Williams out of her dangerous predicament and in the meantime falls in love with her.
