Based on a 1957 play of the same title by Ronald Alexander,[4] the film stars Clifton Webb, Jane Wyman, Jill St. John and Carol Lynley.

Robert Dean is an old-fashioned psychologist who reluctantly allows his oldest daughter Meg to join a four-week tour in South America before returning to college.

When he learns that she is planning on six more weeks in São Paulo, he travels to Brazil, accompanied by his wife Mary and younger daughter Betsy.

Carlos makes a horrible impression on Robert, who tries to prohibit Meg from seeing him by booking a flight for the family to Rio de Janeiro and then on to Lima.

After bidding Meg farewell, Robert visits a bar, gets drunk and falls unconscious on the street, where he is mistaken for a member of a Spanish tour group.

[5] In a contemporary review for The New York Times, critic Bosley Crowther called the character of Robert Dean a "disgustingly old-fashioned creature" and panned the film: "It is a thoroughly silly story, which is not in the least improved by the wishy-washy acting of everyone involved.

What is even more remarkable, Miss Lynley manages all this despite the almost incredible obstacle presented by having to play opposite the hopelessly untalented Mr. Gary Crosby impersonating a sergeant.
