Young-sae was one of the best dancers in Korea, as we witness in the opening to the film. He dances beautifully with his love and protégée Se-young in the middle of dance competition, until his rival Hyun-soo signals to two other dancers to “accidentally” knock Young-sae over and “mess up” his leg. Se-young later goes to dance with Hyun-soo and Young-sae spends his time a depressed wreck living in his messy apartment without a desire to dance.

Two years pass until Young-sae’s friend forces an imported Chinese girl upon him as his new partner. The girl is supposed to be Jang Chang-min, a girl with some dance experience, but her younger nineteen-year-old inexperienced sister comes in her place. Still, Young-sae decides to teach her dancing from scratch in the next three months before the annual dance competition and his dramatic comeback.
