If dogs are man's best friends, then, according to Im Soo Jung's (A Tale of Two Sisters) latest melodrama Lump Sugar, horses are woman's best friends. The career of director Lee Hwan Kyung (not to be confused with the writer of Yeon Gaesomun and Emperor Wang Gun) certainly defies expectations. After working as assistant for acclaimed directors like Lee Myung Se and Park Jong Won in films like Rainbow Trout, Lee opted for the less economically rewarding but safer road of TV producer at MBC. A couple of years later, he was back in cinema, directing the romcom He Was Cool with Song Seung Hun and Jung Da Bin. Lee Hwan Kyung now presents his second film, Lump Sugar, which earned both success at the box office and good reviews, especially for Im Soo Jung's (and the horse!) performance.

Growing up alongside her horse CheondungI, motherless Si Eun (Im Soo Jung) builds an increasingly strong bond with the animal. They don't need words to communicate, just gestures, eye contact, and trust in each other both on and off the racing field. One day the horse is sold, and Si Eun's life seems to stop in its tracks. Two years later, Si Eun is striving for her dream of becoming a successful jockey when she meets an old friend on the field.
