A child, Mary Sunshine, filled with a desire to play with other youngsters, was forbidden to do so by her mother. But one day Piggy, a young negro child, appeared over the top of the fence and the temptation was too great. From that day on, Mary was given to running off with Piggy. As punishment for her first offense, she was sent to bed without supper, but neither her father nor mother could sleep when they realized that Mary was hungry, so they caught each other bringing food to the youngster. On a nearby estate lived Daniel Graham, rich, alone and grouchy. To him came the awakening when he heard the laugh of a child. Looking over the fence to locate the laugh, he found Mary and Piggy encouraging a chicken fight. From then on, day after day, the child visited him and brought cheer to the big mansion, which had never known the sound of childish laughter.
