I don't think it happens in the stage show, but I think of the nuns at the end of the movie of The Sound of Music who sabotaged the Nazis' cars so that the von Trapp family could get away. And the Nazis also know, thanks to Rolf, that the nuns were hiding the family. The poor nuns probably got tortured and killed by the Nazis as a result. I guess the audience is supposed to think that the family got away, so who cares what happens to the nuns? But, even as a child, I thought the fate of the nuns made the ending a not-completely-happy one.
