Two little angels, Nicole and Penelope, ages 4 ½ and 6, come into the life of a widow living in a little house near the village of Winnetka. They arrive after school, make themselves completely at home and bring joy into “Emily’s” life. Winnetka is stunned by two murders, and then the “kidnapping” of Nicole and Penny’s baby brother. All ends happily when the girls remember where they took “Donny” when the nurse was not watching.
