An old beggar woman is standing in front of a beautiful mansion asking for alms when the inhabitants of the place come along. They give her a little change but not enough to satisfy her and when she tries to get more the butler orders her away and slams the door in her face. Infuriated at the treatment the old woman leaves vowing vengeance. In the afternoon the housemaid has the baby out in the park, and while she is seated on a bench conversing with a friend the old hag steals the child out of its carriage and makes away without being seen. When the maid misses the youngster she returns and tells the grief stricken parents the sad news. They have a noble dog, and when he sees the family in tears he realizes that the baby is gone, so without being seen he steals out of the place and starts on a long run in search of the little one. His instinct leads him to the door of the hut where the old hag has the baby, and entering he sees the little one on a mattress on the floor while the old woman lies in a drunken stupor. The dog retraces his steps back to his master’s home and whines and barks until he attracts attention and causes his master to realize that he is up to something. Finally the man follows the animal and he leads him to the place where upon entering he is overjoyed to find the lost baby. He takes the little one back to the distracted mother who is thankful to have her darling returned to her, and the noble dog comes in for his share of the adulation for performing such an intelligent act.
