Titane

During a tumultuous car ride, a young girl named Alexia creates chaos, leading to a severe accident. This incident results in a catastrophic skull injury that necessitates the surgical insertion of a titanium plate in her head.

After a lengthy hospital stay to recover from her injuries, Alexia returns to her home. However, she becomes increasingly alienated from her parents and develops a bizarre obsession with cars.

Years later, now an adult, Alexia captivates audiences as a provocative showgirl at a car exhibition. Despite her seemingly glamorous life, her past and dark side simmer beneath the surface.

After a male admirer confronts Alexia outside the show, professing his unexpected love, she feels threatened. In a shocking act of self-defense, she uses a metal hairpin to kill him, marking the start of her violent spree.

In the aftermath of the murder, Alexia washes herself clean and finds herself drawn to a car she modeled with earlier. The car mysteriously activates, leading her into an inexplicably euphoric experience.

As she maintains her exterior life, it becomes evident that Alexia is a serial killer. She continues to take the lives of numerous victims while keeping her violent tendencies hidden from her family.

Alexia discovers she is unexpectedly pregnant, a shock to her lifestyle. In a desperate act, she attempts to abort the child using her hairpin, but her efforts prove futile.

At a house party, Alexia becomes intimate with Justine, but the encounter ends in tragedy. In a fit of bloodlust, she murders Justine and goes on to kill the other guests, with one narrowly escaping.

Overwhelmed by her dark life, Alexia decides to burn down her home. With her parents trapped inside their locked bedroom, she commits this horrific act, severing all ties with her previous life.

Now a fugitive, Alexia transforms her appearance, adopting the identity of Adrien, a boy who vanished a decade earlier. This drastic change allows her to enter Vincent’s life, unaware of his suspicions.

Vincent, Adrien's father, introduces the new 'son' to his team at the fire station. Despite initially raising concerns about Alexia's silence and androgynous appearance, Vincent's protective instincts deepen.

When Vincent faces health challenges from steroid misuse, Alexia hesitates to reveal her true identity. She remains supportive, deepening their unusual bond and complicating her already perilous situation.

The tension escalates when Vincent's estranged ex-wife visits, unknowingly confronting Alexia's secret. Despite her pregnancy becoming apparent, Alexia keeps her truth hidden to preserve Vincent's delusion.

As Alexia's condition worsens, revealing her mechanical nature, she finally confesses to Vincent. In a climactic moment, he assists her during childbirth, leading to a shocking turn of events.

The traumatic childbirth takes a deadly toll on Alexia, leading to her demise. Vincent is left holding their newborn, whose spine contains titanium, as he grapples with his grief, whispering comforting words.
