Nine disagreeable Britons representing different social/economic classes are mysteriously transported to a place with a door. As they wait for the door to open, we get to know them better. Eventually the door opens, and they go explore a city which the audience never sees. T The idea is that post WW2, England should become a more fair and equitable society with people who treat each other well. When the characters find themselves in such a city they have different reactions. It's interesting how some of the selfish ones try to emotionally drag those who want to live in the city back to their miserable lives. There is an episode involving a mother and daughter that is very similar to an episode in C. S. Lewis' novel "The Great Divorce" written 12 years later. It made me wonder if Mr. Lewis ever saw the film. Note: "They Came To A City" is similar to watching a stage play. At only 66 minutes long it's worth a look.
