So-yeun is an animal groomer who works in a pet shop. One day, she gets stuck with a Persian cat named Silky after its owner suddenly dies. From then on So-yeun is constantly haunted by a bobbed hair girl with green cat-like eyes who turns her life into turmoil. So-yeun desperately seeks help from the people around, but no one will listen.
The presence of the girl and the sound of Silky’s cries start to happen more often in and around her life, and to make matters worse, the people around her start to dye one by one. In hopes of stopping the madness, So-yeun gets rid of Silky, but the cat mysteriously keeps returning. Terrified she could be the next to die, So-yeun sets out to find out the identity of the girl and in the process, discovers the truth behind a tragic incident that took place many years ago.
