Hiroshima-born Sadako is lively and athletic--the star of her school's running team. And then the dizzy spells start. Soon gravely ill with leukemia, the "atom bomb disease," Sadako faces her future with spirit and bravery.

Recalling a Japanese legend, Sadako sets to work folding paper cranes. For the legend holds that if a sick person folds one thousand cranes, the gods will grant her wish and make her healthy again.
