Titane Plot Summary and Synopsis
As a little girl, Alexia is severely injured in a car crash and has a titanium plate fitted into her head. When she gets out of the hospital, she shuns her parents and kisses their car passionately.
Years later, Alexia, now an adult and wearing a large scar on the back of her head, works as a sexed-up showgirl at a motor show. There, she flirts with Justine, one of her coworkers.
When an enamored male fan clumsily attempts to seduce Alexia after a show, she brutally murders him using her large hairpin. Later, Alexia, still eerily attracted to cars, climaxes by rubbing herself inside a car while alone at the Club’s garage.
It is revealed that Alexia is a serial killer who has murdered several men and women in the past few months. She still lives with her parents, who seem unaware of her connection with the crimes and with whom she has a distant relationship.
Eventually, Alexia realizes she has somehow become pregnant. She tries to have an abortion with her hairpin but fails.
Alexia is later seen at a house party, where she has sex with Justine. She murders her and proceeds to kill the other guests. However, a woman manages to escape. Alexia returns home and sets her own house on fire, purposely killing her parents in the process.
Now wanted for murder, Alexia alters her appearance by shaving her hair, taping down her breasts, and breaking her nose. She then goes to the police pretending to be Adrien, a young boy who disappeared ten years before at age seven. Adrien’s father, Vincent, recognizes Alexia as his missing son and refuses to do a DNA test.
Vincent, a fire captain, takes Alexia to the station where he lives and works and introduces her to his men. The firefighters are puzzled by the mute, androgynous, and apparently traumatized ‘Adrien’, but they refrain from questioning their captain’s behavior.
Alexia becomes an apprentice at the station, under Vincent’s supervision. As Vincent gives more responsibility to his “son” instead of the other experienced firefighters, one firefighter confronts Vincent about ‘Adrien’s’ identity. However, Vincent immediately shuts him down and tells him to never speak of his son.
Vincent is a tortured man who tries to preserve his strength by injecting hormones into his muscular, aging body. Alexia is gradually disturbed by his possessiveness and considers escaping from the fire station. However, after Vincent attempts suicide, she chooses to remain with him.
Over time, maintaining her masquerade becomes more and more difficult for Alexia as her pregnancy progresses.
Vincent’s long-estranged ex-wife comes to see her ‘son’, but soon discovers that the person posing as Adrien is a heavily pregnant woman. She nevertheless keeps the secret for herself, not wishing to interfere with her ex-husband’s delusion.
Alexia’s body gradually breaks down, as new metal plates start appearing from under her skin and she exudes what appears to be motor oil from her breasts and vagina. As her pregnancy eventually comes to term, Alexia reveals her real name to Vincent.
Titane Ending
Alexia dies after Vincent helps her giving birth. Vincent, in tears, holds the baby, whose spine appears to be made of titanium.
