The story of Just Believe begins with a children's choir preparing to leave on a Christmas tour to the Big City Convention Center to perform. Unfortunately, their bus driver breaks his leg and is unable to drive to the event. Miss Lila prays for direction and feels the Lord is leading the children to sing at the Heavenly Peace Retirement Center across the street. The children are not thrilled with the idea because they long for the lights and glamour of the convention center. The children meet Grandpa Eddie, Miss Mary, and Miss Daisy, some wonderful seniors, who teach them about Christmases of old and the true meaning of Christmas. The mission project for this musical is to encourage every choir performing Just Believe to adopt a senior citizen's center at Christmas. Hopefully this musical will help children everywhere to look for the light of Jesus when a door is closed to them.
