Neglected by her grief-stricken father, a doctor, after the tragic death of his wife, little Eileen Homer changes the wording of her father's ad for a governess to read: "Wanted, a mother." A laborer named Giuseppe asks Dr. Homer to operate on his ailing son, but when the boy dies, the enraged father attacks the doctor. Eileen meets her father's friend, Dr. Thelma Winter, and that night, while dreaming that Dr. Winter has become her fairy mother, she walks in her sleep to the edge of the lake. Wandering aimlessly in his grief, Giuseppe rescues the girl and takes her home to fill the void left by the loss of his son. In trying to return home, Eileen falls from the fire escape and is rushed to the hospital, where Dr. Winter saves her life. Afterwards, the grateful Dr. Homer becomes a more loving father with the help of his new wife, Dr. Winter, and Giuseppe becomes the family's gardener.
