Brigadoon

    While in Scotland, Tommy, engaged to a young woman he's not sure he loves, and Jeff, a cynical alcoholic in the making, find Brigadoon, a town not on any map. Tommy also finds Fiona, with whom he falls in love, but then discovers that the town and its people come to life only once every hundred years--and will be destroyed if one of its inhabitants leaves. Harry, in love with Fiona's sister Jean, who is marrying Charlie, decides to break the spell but is accidentally killed  by Jeff as he is escaping. Although Tommy wants to stay, Jeff convinces him to return to his fiancee and New York. Back home, Tommy sees he's made a mistake and returns to find Brigadoon. He does, because his love for Fiona is so strong.
