Ladybug, Ladybug

The teachers and students of a countryside elementary school are thrown into a panic when an air raid siren goes off, warning them of an imminent nuclear attack. They are unaware that it has gone off by mistake, and separate the children into groups -- one of which is headed by the anxious Mrs. Andrews (Nancy Marchand) -- to take them home. Harriet (Alice Playten) invites her classmates into her family's bomb shelter, but tragedy strikes when she won't allow one of her classmates to enter.
