A young boy grows to adulthood believing his father was the man responsible for a murder committed during a bank robbery.

Two identical twin sisters, separated at birth by their parents' divorce, are reunited years later at a summer camp, where they scheme to bring their parents back together. The girls, one of whom has been living with their mother and the other with their father, switch places after camp and go to work on their plan, the first objective being to scare off a gold-digger pursuing their father.

This musical version of the tale of the boy who wouldn't grow up aired live on television on March 7, 1955. It was so popular that it was restaged the following year, and again four years later.
