Two Americans, Tommy Albright and his pal Jeff Douglas, chance upon a small Scottish village in a Highland mist. They discover, mainly from the village schoolmaster Mr Murdoch, that Brigadoon is an enchanted place that only comes to life for one day in every hundred years.
Tommy and Jeff meet Fiona MacKeith and Meg Brockie, and Tommy and Fiona soon find in each other a deep understanding.
We follow the villagers through a day that includes a wedding, where we see the gathering of the clans, and learn that if one of the inhabitants should leave Brigadoon the spell will be broken for ever.
There is a near disaster when a young embittered Scot, Harry Ritchie, tries to take his revenge upon Charlie Cameron for stealing the heart of Jean MacKeith. He dashes towards the forest but is killed making his escape. Happiness is changed to mourning.
Tommy has by now fallen in love with Fiona but he is told he cannot stay in Brigadoon. He goes back to New York with Jeff and quarrels with his fiancee. Suddenly in a New York bar he sees a vision of Fiona and comes to a decision. He knows he must return to Scotland.
There, by the power of love, he reawakens the slumbering Brigadoon just long enough for him to be reunited with Fiona.
