The girl group Pink Dolls, which consists of A-rang, Je-ni, Shin-ji, and Eun-ju, make their debut on stage but fail to achieve popularity. They and the record company moved to a renovated studio that was burnt down in a fire 15 years ago. Eun-ju's sponsor (someone who funds an idol or group on the condition they receive sexual favors) was credited for making the move, and renovations happen. Eun-ju is bullied by the other three members for her involvement with the sponsor and considers quitting. Her vocal trainer and friend, Soon-ye encouraged her to remain in the group as she believes they will find success and gain attention with their new song. While cleaning up in the dance rehearsal room, Eun-ju finds a VHS tape titled "WHITE" and plays it in her dorm room. The footage is of an old, grainy unreleased music video. When the group's manager finds her watching the tape, she demands to permit its song to be remade as their next single.

When Pink Dolls become popular with their debut of the song "White," which has become a viral sensation, the manager seeks to re-record the song but with the main vocalist overtaking the song. Tensions begin to rise as Je-ni, A-rang, and Shin-ji become hostile and jealous against each other as they fight over the spot. While still trying to figure things out, a ghost haunts and attacks the three members on different occasions; Je-ni by strangling her with microphone cords, A-rang by causing her to fall off a music-video set, and Shin-ji by crushing her with camera equipment. Fearing the song is cursed and that she will be the next victim, Eun-ju examines the video with Soon-ye and an editor and from there believe that a trainee named Jang Ye-bin, who died before the studio caught fire, wrote the song. Eun-ju meets up with her sponsor and asks about the circumstances surrounding Ye-bin and replies that she died by suicide. After returning to the rehearsal room in a fit of depression, Eun-Ju finds a suicide note beside power sockets that may have started the fire and she smashes the sockets with a hammer until she fell asleep in the morning. Eun-Ju along with Soon-ye and the editor make a small memorial for Jang Ye-bin, she asks Jang to leave them be and that she should Rest In Peace.

Confident that the curse is broken, Eun-ju decides to get more attention by reinventing "White" with a new image, including dressing and dying her hair in white, and using the stage name "White"; but she takes credit for the song to her solo performance and alienates those around her. While Soon-ye was destroying the evidence, she re-watches the video and noticed new details they had never seen. While doing so, she and the editor learned that Je-ni, A-rang, and Shin-ji, who had been hosts for a music television show, died from drinking bleach on air.

Soon-Ye and the editor check the music video and she hears something strange in the middle of the song and has the editor check it out. While doing so Soon-Ye calls Eun-Ju trying to warn her, but she does not answer her phone. Soon-Ye realizes that they shouldn't check the song, but it is too late as the editor had already modified the song via a special sound software. When they listen to what is left, they repeatedly hear "hey, behind you" at the same time they see the ghost's apparition in the music video behind the lead singer Jang Ye-bin.

Soon-ye calls Eun-ju, who is on her way to a venue to perform "White," and warns her that the curse is not over but angrily refuses to listen. Soon-ye soon learns that the writer of the song was not Ye-bin but was a back-up dancer White who was bullied by Ye-bin, who disfigured her face with acid and forced the back-up dancer to commit suicide by drinking bleach. Her ghost killed Ye-bin, who caused the fire when attempting to burn the suicide note along with the music sheets for the song white.

Soon-ye rushes to the venue to rescue Eun-ju but is unable to enter the stage with all the doors being locked. During Eun-ju's performance, White causes the power to go out, and causes the electricity to malfunction. Eun-ju's sponsor and manager tries to get her off the stage, but they are both killed by stage equipment, one of them is electrocuted and the other is burned alive by sparklers that explode right in her face.

The ghost White appears and slowly creeps toward Eun-Ju terrifying her. Suddenly, the doors all open, and the panicking crowd start to rush out of the building, Soon-ye enters and she and Eun-ju attempt to reunite, but Eun-ju trips in the crowd and gets trampled to death. The electricity eventually sets the venue on fire at the same time Soon-ye simultaneously sees Eun-ju dead on screen when a camera falls in front of her and spots white's ghost on the stage and is dragged away by security.

In a flashback, Jang Ye-bin is shown bullying the dancer and writer White and eventually forcing her to drink bleach causing her death. It is then that Jang Ye-bin stole her song "white" and starting dressing as her as well. Which included dyeing her hair white and wearing white clothing as well. When she performed for the music video shoot, she noticed something was not right and when she checked the footage she saw White's ghost in it. She freaked out and in the end decided to burn her suicide note and White's music sheets. But as she did, White's ghost suddenly appeared terrifying Jang Ye-bin causing her to drop the burning music sheets spreading the fire and to beg for mercy before she was killed by white.

After the incident, Soon-ye is shown destroying all of the remaining evidence of the song in the studio's karaoke room while mourning her best friend's death. However, to her shock the karaoke machine announces that the next song playing is "White," alluding to the possibility that the curse has not been broken.
