It is summer in Euharlee, Georgia, and Imogene Lavender's garden is bursting with snap beans, okra, and tomatoes. The household -- made up of Imo; her daughter Jeanette and her new baby; and Lou, Imo's niece -- is about to grow as well. Imo's estranged mother, Mama Jewell, has begun to show signs of senility, and Imo has decided that it is her duty to take her mother in. Mama Jewell brings with her some secrets from the past, including the story of Lou's mother, a revelation that sends Lou in search of her ne'er-do-well father. For Imo, who is feeling the squeeze of being in the middle of the generations, Mama Jewell's temperamental nature stirs up long-buried memories of a difficult childhood. And much to everyone's surprise, wild Jeanette is so determined to find a husband that she joins the church choir to be closer to the handsome and enigmatic young reverend.
