When lawyer Frank Michaelson and his wife, Anne, send their daughter, Mollie, to college, they soon discover that boys are not the only danger to her reputation. She soon becomes involved with beatnik folksingers and "Ban the Bomb" demonstrators, and Frank finds himself in several humiliating situations when attempting to help her. Matters are made worse when Mollie goes to Paris on an art scholarship. Seeing in Life magazine that Henri, a young artist, is painting her in the style of Picasso, Frank flies to France, but in Paris he only causes more confusion when he is accidentally arrested in a police raid on a shady bistro. Mollie finally confesses her love for Henri and introduces him to her harassed father at a costume ball; all goes well until Frank's Daniel Boone costume disintegrates, and he falls into the Seine. But true love triumphs over petty adversities, and the young couple are married. Frank returns home to begin worrying about his younger daughter, Liz.
