Sound engineer Sang-woo meets local DJ Eun-soo on a recording trip in the quest for nature's voice. They succeed in capturing various sensual sounds as well as each other's tenderness. Their love flourishes as spring comes along, but Sang-woo's ever intensifying passion often reminds Eun-soo of her tragic past. She knows only too well how passion can vanish like a sound, and how love always surrenders to its end.
