Ultra-pasteurized pop singer Pat Boone makes his feature film debut in this comical and tuneful look at adolescent life in the late 1950s. A group of teen-age boys discuss the attributes of the perfect girl and proceed to create a mental image of their dreamboat. Later they find her in the form of Jean, the new telephone operator in town. One of the lads, Sanford Wilson, falls hard for the comely lass. They begin dating, but as final exams approach, Sanford must temporarily shift his attention to his school work. To keep her from the other less-honorable boys who want her, he has handsome Lieutenant Langley Beaumont squire her around. Unfortunately, she and Langley soon fall in love, causing the anguished Sanford to join the military and leave for a year and a half.
