Take Her, She's Mine (1963)

Jimmy Stewart plays a cautious father to Sandra Dee, who is going off to college. He gets so worried that she is doing things that she's not supposed to be doing, that he tracks her down at her school, and then tracks her down in Europe. What's even worse is that he has to explain his actions to the members of a school board regents in order to keep his job on that board.
