“Where we go one, we go all” is a quote from White Squall - a 1996 movie about a group of people surviving on a ship through a great storm.
In 1960, a hardy group of prep school students boards an old-fashioned sailing ship.

Thank you.
I did look it up, but I did not think to do so until right after I had posted that question.
The synopsis I saw mentions a part of the plot line that dovetails with the Q message. It says that people attempt to turn the members of the boat crew against one another but they remember to live by their motto.
