Park Mina, a highly popular singer who's won the hearts of many fans, gets into a car accident when her car swerves to avoid an oncoming vehicle. The car, which fell into a ditch, explodes and causes Mina to suffer second, third and fourth-degree burns on her body.
Mina's manager Kang Joon-seo happens to find Kim Soo-ryun, who looks almost exactly like Mina. Joon-seo initially asks Soo-ryun to take Mina's place for a short period of time until the real singer recovers. Soo-ryun agrees to the proposal because she badly needs money for her mother's surgical fees and her brother's tuition. After undergoing rigorous training from Joon-seo, Soo-ryun emerges as a near-perfect replica of Mina. However, Soo-ryun falls in love with Mina's boyfriend Jung Tae-hoon, and becomes enamored with fame and fortune.
Meanwhile, the real Mina returns, but the plastic surgeons were unable to restore her original appearance. Joon-seo, thinking that fans would not accept her new face, refuses to allow Mina to continue her singing career. Mina goes on television to reveal her true identity, and as Tae-hoon begins to investigate, Soo-ryun and Joon-seo feel threatened.
Mina later learns that Soo-ryun is her identical twin sister, and they had been abandoned at a Catholic orphanage after birth.
Soo-ryun asks Tae-hoon to forgive her, but he rejects her when he realizes that Joon-seo and Soo-ryun conspired to prevent the real Mina from coming back.
Depressed, Soo-ryun attempts to commit suicide. But Joon-seo stops her in time and tells her to prepare her final performance as Mina.
