When his mother dies, James Earle (Sugar) Martin goes to live with his uncle Free, a gruff crippled man who makes his living fishing in a swamp in the Mississippi Delta. At first Sugar and Uncle Free barely get along, and Sugar is afraid of the swamp and everything associated with it. The only bright spot in Sugars life is the building of the new Sweet Kingdom Church, which will be adorned with a beautiful stained glass window that his mother scrimped and saved for while she was alive. As time passes a budding sense of family develops between Sugar and Uncle Free. Then one day Sugar discovers that the money for Mamas window is being used to construct the church itself. Devastated but unwilling to give up on his mothers dream, Sugar finds affirmation and support where he least expects it. In a truly heartwarming yet unexpected ending, Mamas Window shows us all the importance of hope, dreams, and finding a place to call home.
