Bob Holcomb (Bob Hope) is a widower who worries about his teenage daughter JoJo (Tuesday Weld) in this light romantic comedy. He doesn't care much for JoJo's boyfriend Kenny (Frankie Avalon) because the smooth operator has a motorcycle and some money. Bob manages to get his company to transfer him to Sweden, which effectively separates Kenny and his daughter. JoJo adapts to her new surroundings and starts to date Erik Carlson (Jeremy Slate), an idle playboy and lothario. All of a sudden, Kenny seems all right by Bob, who tries to convince him to come to Sweden and fight for the woman he loves. Bob's new flame Karin (Dina Merrill) is less-than-sympathetic to Bob's babbling about the double standards he sets for his daughter. Maudie Prickett plays a man-hungry spinster, and the musical group The Vulcanes help out with some of the feature's 12 songs.
