In pursuit of a triumphant comeback, a former dancing star imports a teenage phenom to play the role of his partner, only to discover that she barely has any experience. Can he train her to dance like a champ in just three months?

Former acclaimed dancer Na Young-sae (Park Keon-Hyeong) attempts to make a comeback after his opponent Hyun-soo (Yoon Chan) purposely injures him at a dance competition. At the suggestion of dance-studio manager Ma Sang-doo (Park Won-sang), Young-sae brings to Korea Jang Chae-rin (Moon Geun-Young), an ethnic Korean from China whom he presumes is a renowned, talented dancer. To his surprise, Young-sae learns that Chae-rin knows nothing about dancing: her soon-to-be-married older sister Chae-min is the talented dancer. With only three months until the national dance championship, Young-sae trains Chae-rin, vowing to turn her a world-class dancer.—Wikipedia
