In the 1960s, Frances "Baby" Houseman, goes with her family to a resort in upstate New York's Catskill Mountains. All expect her to go on to college, before marrying a doctor, just like her father. Unexpectedly, Baby becomes infatuated with the camp's dance instructor, Johnny, a man whose background is vastly different from her own. Baby lies to her father to get money to pay for an illegal abortion for Johnny's dance partner. She then fills in as Johnny's dance partner and they fall in love. It all comes apart when Johnny's friend falls seriously ill after her abortion and Baby gets her father, who saves the girl's life. He then learns what Baby has been up to. He bans his daughter from any further association with "those people". Baby later sneaks out to see Johnny and ends up consummating her relationship with Johnny. A jealous fellow vacationer sees Baby sneaking out of Johnny's bungalow the next morning and in an act of retribution, tells management that he is responsible for a theft the evening before. In an act of bravery, Baby states that Johnny is innocent, and alibis him by confessing that they were together all night. This revelation causes a huge rift in the family. At the closing night performances, and although he has been fired and banned from attending, Johnny returns and takes the stage to tell everyone about the woman whose faith in him and whose courage changed his life. They do one final show-stopping dance together. Baby's father learns that Johnny was not responsible for his partner's pregnancy and learns to accept that although his beloved daughter is transitioning to womanhood, she will always love him.
