One of the subplots involves Fred (Murray Hamilton) and Edna Ferguson who take their nineteen-year-old daughter Shelly (Hilarie Thompson) on the tour to get her away from her boyfriend in the U.S. On the trip, she falls for an intriguing student radical named Bo who organizes protests across Europe. Edna was played by Peggy Cass, who was also a regular panelist on various television shows in from the 1960s to the 1980s, including the popular To Tell the Truth (1956) in its heyday. Bo was played by Luke Halpin, who became famous in the early to mid 1960s as the star of two movies and the television series Flipper (1964), playing Sandy Ricks. Luke's rising fame saw him appear as a 'contestant' on To Tell the Truth (1956) in March 1964 just before he turned seventeen. Peggy Cass was one of the four panelists who quizzed Luke (and the two other impostors) in an attempt to determine the real Luke Halpin. She was the only one of the four to make a wrong choice.

As promised by the tour company, the tourists get to see nine countries: England -> Holland -> Belgium -> Luxemburg -> West Germany -> Switzerland -> Lichtenstein -> Italy -> Vatican.

During one of the interludes that Shelly Ferguson (Hilarie Thompson) spends with the free-spirited Bo (Luke Halpin), she admires the slogan "Suppose They Gave a War and Nobody Came" that he has displayed on his motorcycle. That phrase is also the title of the next (and last) movie, Suppose They Gave a War and Nobody Came (1970), in which their co-star, Pamela Britton (Freda), appeared before her untimely death in 1974.
