Kellerman mountain late summer 1963, Frances·and their parents, a sister came here on vacation. Frances, who is still in school, is a 17-year-old decent girl. She is not cold about boys, dance lessons and family games.
One night, by chance, she entered a hotel and found that a dance party was being held there. To her surprise, the people here are all clinging to each other, dancing frantically. This is the "dirty dance" full of erotic atmosphere. At this time, dance coach Johnny Castlecame to Frances who was at a loss, dispelled her worries, and taught her the basic dance steps. In the process of learning, Frances fell in love with Johnny. For fear of being fired, Johnny dared not develop this relationship.
At this time, Johnny’s dancing partner Penny was pregnant with Robbie’s child. Frances asked his doctor’s father to consult with Penny. The father thought that Penny’s pregnancy was caused by Johnny, so Frances was not allowed to interact with him, but Frances carried him on his back. Father is still dating Johnny secretly. A customer who lost his wallet accused Johnny of doing it, and Johnny lost his job. Frances' father now knew the true father of Penny's child, and blamed Johnny for right or wrong. Johnny returned at the end of the summer party. He danced with Frances, and his graceful dance dazzled everyone.
