Han-na is an overweight phone sex
employee and a ghost singer for Amy, a famous pop singer who actually lip
syncs. Instead of being famous for her own amazing vocal talent, Han-na hides
behind Amy's performance stage and sings during Amy's concerts, and records all
of Amy's songs. One day, Amy ungratefully humiliates her in front of the music
company's director Sang-jun during his birthday party, knowing full well that
Han-na has a crush on him. While crying in the bathroom, Han-na overhears
Sang-jun telling Amy that even though they are just using Han-na for her voice,
they must be kind to her so she will not walk out on them. Heartbroken, Han-na
attempts suicide but is interrupted by a phone call from one of her phone sex
regulars who happens to be a top plastic surgeon. She decides to get
head-to-toe plastic surgery instead. The surgeon at first refuses to operate on
Han-na, but Han-na threatens to blackmail the surgeon by telling his wife about
his calls. Then, Han-na makes a moving speech that she does not want to undergo
surgery merely to be beautiful, but for the sake of love and as a boost in
confidence, and the surgeon is deeply moved. Han-na puts herself in seclusion
for a year as she recovers from the changes.
When she comes back from the
hospital, Han-na is incredibly beautiful and slender. No one, not even her best
friend, Jung-min, recognizes her. With Jung-min's help, she creates a new
identity for herself; she is now a Korean-American from California named Jenny.
After auditioning to be Amy's secret vocalist again, she earns her own
recording contract instead from Sang-jun, claiming that she is
"all-natural". In the meantime, Amy, oblivious just like everyone
else of Han-na's new identity, desperately tries to find Han-na so that she can
record her own postponed album (since she cannot sing the songs herself) by
spending time with Han-na's father who is in a hospital due to mental problems,
possibly Alzheimer's. Meanwhile, romance begins to blossom between Jenny and
Sang-jun, as he continues to promote Jenny, in effect boosting Han-na's
confidence in her new self. However, Amy, through spending time with Han-na's
father and Jenny, eventually realizes that this Jenny is actually Han-na in
disguise.
During a date one night, as
sparks fly, Jenny strips for Sang-jun in the character of a nurse, through a
phone sex session. After Jenny has fallen asleep, he sees the African character
Jenny had drawn on the glass and realizes that he had seen it before. He
remembers that Han-na had drawn exactly the same signs on a sheet of music.
Then he adds up all of the signs and realizes as well that Jenny is actually
Han-na but he keeps this information to himself.
Jenny's debut single
"Maria" becomes a hit and the recording company holds a party to
celebrate its release. On the day of the party however, Amy brings Han-na's
father in an attempt to blow her cover. Han-na's father tries to return
Han-na's Barbie doll to her, which had always been Han-na's favorite childhood
gift from him. Startled by the sudden appearance of her father and not knowing
how to react in front of all the people, including Sang-jun, Han-na denies
knowing her father and calls him a fan instead when Sang-jun asks her if the
old man is her guest. As her father keeps insisting on giving her the doll,
Sang-jun drags him away from Jenny and accidentally knocks him down onto the
floor. Desperate to keep her true identity a secret, Han-na makes no move to
help her father. It is Jung-min who finally helps him up, casts Jenny a furious
look and leads Han-na's father away from the party.
After the party, Sang-jun and
Jenny are the only ones left in the room. Sang-jun reveals to Jenny that he
knows her true identity but is now cold and distant. He seems unable to forgive
her for lying to him but says that he will still work to promote Jenny and
carry on with her concert scheduled the next day. Han-na breaks down at this
point, heartbroken and unable to pretend to be someone else anymore. Han-na
tells him that it is incredibly frustrating and painful not being able to just
be herself but have to live a lie, especially in front of him. The surgery that
took a whole year to recover from was not nearly as painful as realizing that
she still could not be close to Sang-jun. As Sang-jun tries to comfort her, she
brushes away his efforts saying, "You broke my heart. Tissue paper cannot
fix it."
Sang-jun still insists on
continuing with Jenny's first concert, despite protests from the company boss.
Later, he encourages a distraught Jenny to do this concert, not for the sake of
the fans or the company but for herself, thus implying that he has forgiven her
and will continue to support her. At the concert, Jenny can't sing and later
breaks down from the pressure of seeing her father being dragged away by
security and tells everybody to stop. She then reveals to the public that Jenny
is a "fake," and that she is not "all-natural", as she had
claimed, but is "plastic". However, nobody seems to believe her. She
proceeds tearfully to tell the large crowd her story: how she has abandoned
everything that is dear to her - her best friend and father - to get to where
she is. She also tells the crowd about how on the way to fame and fortune she
has also lost her own identity and that she now no longer knows who she is.
Just then, the screens behind her on the stage start to show a clip of the old,
obese Han-na, singing angelically. Han-na turns around and sees her old image
and tells the crowd that the image is the real her. The crowd, moved by her
sincere confession, responds by chanting "It's okay," and Han-na
rekindles her relationships with her father and best friend. She drops the
stage name Jenny and re-releases a CD with her own name, Han-na, and becomes a
highly successful music artist, gaining many fans and anti-fans along the way.
Sang-jun realizes the very thing about Han-na that had always drawn him to her
was Han-na's innocence. However he also realizes that she has moved on and is
now content with who she is.
At the end of the movie, Jung-min
also asks to get head-to-toe plastic surgery.
