Takes place inside an American embassy behind the Iron Curtain. An American tourist, a caterer by trade, and his family of wife and daughter rush into the embassy two steps ahead of the police who suspect them of spying and picture-taking.

But it's not much of a refuge, for the ambassador is absent and his son, now in charge, has been expelled from a dozen countries and the continent of Africa. Nevertheless, they carefully and frantically plot their escape, and the ambassador's son and the caterer's daughter even have time to fall in love.
