Biography[]

A little girl named Alexia is seen irritating her father during a drive home. As she removes her seatbelt, her father turns around to scold her, causing a car crash. Alexia suffers a terrible skull injury and has a titanium plate implanted into her head. When she gets out of the hospital, her personality changes as she shuns her parents and embraces their car passionately.

Years later, Alexia, now a young woman and bearing a large scar on the side of her head, works as a sexualised showgirl at a motor show. While there, Justine, one of her coworkers, flirts with her. One night, after a show, a male fan follows Alexia in the showroom's parking lot, declares his love to her and attempts to assault her; she then brutally murders him using her large hairpin.

When she goes back to shower after washing off the man's saliva, Alexia hears a knock coming from the showroom, naked. She finds the car she modeled before her and somehow it has turned on by itself. Excited, she enters it naked, wraps the seat belts around her arms, inserts the gear lever into her vagina and has sex with the car.

It is soon revealed that Alexia is a serial killer and mass murderer who has murdered people in the past few months, men and women alike. She still lives with her parents, who are 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 perform an abortion with her hairpin but fails.

Alexia is later seen at a house party, where she has sex with Justine. She brutally kills her in the midst of the act and proceeds to kill the other guests. However, a woman manages to escape and presumably alerts the authorities. Alexia returns home and sets her own house on fire before locking her parents in their bedroom, burning them alive. Now wanted for murder and arson, Alexia alters her appearance by cutting her hair, taping down her breasts and increasingly pregnant stomach, and breaking her own nose. She then goes to the police pretending to be Adrien Legrand, a young boy who had disappeared ten years before at age seven. Adrien's father, Vincent, surprisingly 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, myserious, androgynous and apparently traumatized "Adrien," but they refrain from questioning their captain's behavior in fear of losing their job. 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 steroids into his muscular, aging body, but he finds that he seems to be building an immunity to them. Alexia is gradually disturbed by his possessiveness and considers escaping from the fire station. However, after Vincent nearly overdoses on his steroids, she chooses to remain with him out of pity.

Vincent's long-estranged ex-wife comes to see her "son" but soon stumbles on a now-heavily pregnant Alexia without her body taped down. She nevertheless keeps the secret for herself, not wishing to interfere with her ex-husband's delusion. At one point, Vincent accidentally uncovers Alexia's breasts after she showers. Despite this, he covers her back up and promises to keep caring for her regardless.

Alexia's body gradually breaks down, as tears in the skin of her stomach reveal new metal plates and she begins secreting what appears to be motor oil from her breasts and vagina. As her pregnancy finally comes to term, Alexia reveals her real name to Vincent. Vincent helps Alexia give birth, the titanium side of her skull splitting open on her final push, killing her. The birth was successful however the baby's spine is made out of titanium.
