Summary of the musical Brigadoon:
When New Yorkers Tommy Albright and Jeff Douglas get lost on vacation in the Scottish Highlands, they stumble upon Brigadoon. Brigadoon is a mythical village that only appears once every hundred years. At first, Tommy and Jeff are puzzled by the habits and clothes of the villagers. But they are soon charmed: Tommy, who is engaged in New York, falls terribly in love with Fiona, while Jeff flirts with Meg.
It's only when Harry Beaton, Fiona's sister's suitor, tries to leave Brigadoon that the two men realize the complex truth: at the end of the day, this town will disappear in haze for the next hundred years. And if anyone manages to leave Brigadoon, the city and its people will be lost forever.
Tommy has to choose. Will he return to the world he knows and his New York fiancee - or will he try his luck in this mysterious new place?
