Titane

A little girl named Alexia annoys her father during a drive. As she removes her seatbelt, her father turns around to scold her, causing a car crash. Alexia suffers a skull injury and has a titanium plate fitted into her head. When she gets out of the hospital, she shuns her parents and embraces their car passionately. Years later, Alexia, now an adult with a large scar on the side of her head, works as a showgirl at a motor show. One night, after a show, a male fan follows Alexia in the showroom's parking lot, declares his love to her, and forcibly kisses her; she then brutally kills him using her large metal hair stick. As she returns to the showroom to shower, Alexia finds that the tuned Cadillac she modeled with earlier has turned on by itself. She enters it naked, has sex with the Cadillac, and climaxes. It is revealed that Alexia is a serial killer who has murdered three other men and a woman 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. Alexia attends a house party, where she starts to have sex with her coworker Justine. However, motor oil begins secreting from her vagina. She takes a pregnancy test, which returns a positive result, and tries to perform an abortion on the spot, using her hair stick, but fails. She comes out of the bathroom and murders Justine and two other men, but one woman manages to escape. Alexia returns home and tries to burn a bloodied blanket, which sets the house on fire. She locks her parents in their bedroom and leaves. Now wanted for murder, Alexia alters her appearance to pretend to be Adrien Legrand, a young boy who had disappeared ten years before, at age seven, by cutting her hair, taping down her breasts and pregnant belly, and breaking her own nose. She then goes to the police claiming that she is Adrien, where his father, Vincent Legrand, a fire captain, accepts Alexia as his missing son and refuses to conduct a DNA test. Vincent 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 the captain's behavior. Alexia becomes an apprentice at the station, under Vincent's supervision. As Vincent gives more responsibility to his "son" over 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 again. Vincent tries to preserve his strength by injecting steroids into his aging body, but he finds that he seems to be building an immunity to them. Alexia is increasingly disturbed by his possessiveness and considers escaping from the fire station. However, after Vincent experiences an arrhythmia after injecting a large dose of steroids, Alexia decides to stay with him. Vincent's long-estranged ex-wife comes to see her "son", and ends up discovering a now-heavily pregnant Alexia without her body taped down. She nevertheless keeps the secret to herself, not wishing to interfere with her ex-husband's delusion, and begs Alexia to take care of him. Vincent eventually acknowledges his delusion, telling Alexia that "whoever you are, you are my son." When he inadvertently uncovers her breasts, he is shocked but continues caring for her. At a party at the fire station, the firefighters urge "Adrien" to dance to the music. Alexia performs her showgirl choreography, confusing everyone. Vincent, disappointed, walks out of the crowd. After the party, Alexia has sex with a fire engine. Alexia's body gradually breaks down, as the skin of her stomach tears to reveal new metal plates. When her pregnancy comes to term, Alexia reveals her real name to Vincent, briefly attempting to seduce him and before begging him for help as she goes into active labor. Vincent helps Alexia give birth, the titanium side of her skull splitting open on her final push, killing her. The newborn's body appears with patches of titanium on its body. Vincent says repeatedly to the baby, "I'm here."
