The opening scene is a pretty interior, showing the home of the little girl where she is playing with her four-footed companion and friend, an immense St. Bernard dog. her nurse dresses her for the street and she goes out accompanied by the dog, who walks beside her carrying in his mouth a basket intended to hold the little girl’s purchases at the store to which she is going. They visit the store together, the dog carrying the basket in his mouth, and return home to be affectionately welcomed by papa and mama. We next see our little friend being tucked into bed by “nursey,” and affectionate farewell is given to the dog, and next her parents, who -are going out to spend the evening, come in to bid her good-night. They are seen to leave the house and the little girl is left alone save for her nurse and the very faithful dog. In the meantime the nurse receives a visit from her young man and has a “lovely time” entertaining him. His cigar apparently does not draw well and he takes another, throwing away the “stub” without the precaution of extinguishing the light. After this, following the example set by the child’s parents and apparently quite oblivious of her duties, nurse leaves the house with her lover to spend an evening at the theater, and only the dog remains to guard the now sleeping child. Slowly it is seen that the lighted cigar carelessly thrown away is doing its deadly work, smoke is seen to be working its way through the house in gradually increasing volumes, and now the dog becomes aware of it and is plainly very distressed and uneasy. He runs upstairs to effect an entrance into the child’s room, but without success, and seeing it is useless to waste further time he tears downstairs and out on the street, where he finds a policeman. Almost speaking, he induces the policeman to follow him to the nearest fire-alarm box and plainly urges him to call the fire department. This is done and the firemen are soon on the scene with the dog in attendance, who contrives to direct them to the window of the apartment in which the child is sleeping, and none too soon, for the flames and smoke are already pouring from the building. A ladder is put in position, which the fire ladies quickly scale, followed by the dog, whose excitement enables him to perform feats which he could not otherwise accomplish. Knowing the way the dog rushes into the child’s room, who, awakened and terrified by the smoke, has hidden her head under the bed clothes and is on the point of suffocation. The dog seizes the child by the night robe and contrives to drag her from the bed, next across the room and with all care and gentleness, and finally down the stairs and through clouds of smoke which would stifle and overcome many a man. At length the bottom of the stairs is reached; in the meantime the firemen have broken down the door and the child is brought out to the street and restored to the arms of her parents, who have hurriedly returned home on hearing the alarm of fire and are almost distracted with grief at the probably fate of their little daughter. A beautiful tableau of the little girl and her dog ends the scene, which combines more real excitement and intense emotion than has been produced by the moving picture art for a long time.
