Dan King and his girl, Ruth Winters, are sophisticated New Yorkers lost in the heart of Amish Pennsylvania to settle a piece of property owned by Dan's family. Dan has inherited land and has agreed to sell it to Papa Yoder for a wedding gift to his daughter, Katie, and her intended, Ezra. While there, they become involved with the local villagers. Hilda Miller, a spunky Amish maiden, falls for Dan and misinterprets his kind words as words of love. The Amish men tease Ezra about marrying Katie. Ezra's brother Peter, banished from the community for fighting, has returned. He and Katie were childhood sweethearts, and the feelings are very much alive. Dan tries to intercede for the lovers, but stubborn Papa Yoder reminds him that he is a guest in a different way of life. Their adventurous encounters bring Dan and Ruth closer together as they return to New York. Plain and Fancy is presented in concert as part of the York Theatre Company's Musicals in Mufti series.
