Mia Selva watches a woman upstairs leap to her death in the old mansion flats, and at the scene she finds torn fragments of a photograph showing Ludwig Giroux, the man who haunts her past. The image feels like a warning from a future she may be headed toward, and her curiosity pulls her into a dangerous choice: she bribes the kindly caretaker Max to let her search the old woman’s flat. Max warns her not to touch anything, but Mia’s need for answers is stronger than fear. In the flat she uncovers possessions that feel intimate to her—a family photo, pills, and a letter—while a television blinks with the time 2046, hinting at a time beyond her own.
With the lift inside the flat, Mia discovers a shocking secret: a mechanism that lets her move back and forth through time. The device becomes a fragile lifeline as she resolves to avert the tragedy she just witnessed, even as each journey unsettles the present she knows. The mission is personal and perilous, because every alteration could rewrite the life she’s trying to protect.
Her first stop takes her to her younger self, a girl who loves Ludwig yet endures a hard, complicated relationship. Ludwig, a married trumpeter connected to a pub called Harmony, is portrayed as a dangerous temptation. Mia tries to spare her younger self from heartbreak by telling the truth to Stella, Ludwig’s wife Stella, and then confronts her younger self in the aftermath. The encounter is jarring: young Mia is determined to chart her own course, and the moment ends with Mia returning to her present, only to be confronted and teased by Ludwig, witnessed by her younger self, and then dashed by a sudden accident.
Next, Mia is taken to the time of her eighteenth birthday, when she begins dating Ludwig, who is revealed to be old enough to be her father. The attempt to warn her younger self becomes more urgent as Mia races back to the moment when a family photo was taken—the day before her tenth birthday—so she can intervene again. The memories unfold with the discovery that the clown at the park—the entertainer at kid Mia’s party—turns out to be Ludwig, a revelation that upends everything Mia believed about her origins.
Back in their flat, Mia walks with Ludwig to Harmony, where a violent confrontation unfolds: two gangsters who owe Ludwig money close in. She hands Ludwig a bundle of money and urges him to leave for America, hoping to sever the dangerous ties that bind them. The next day, at the birthday party, Ludwig returns and is caught in a compromising moment with Doris, Mia’s mother, an affair Mia discovers with growing horror. Doug, Mia’s father, intervenes and shoots Ludwig in the arm, a brutal glance into the tangled web of desire and betrayal that defines Mia’s life.
Mia seizes a gun during the chaos and escapes with her younger self, only to be chased by the law. She flees, and finally seeks out Max again to travel to the moment when everything began. The trip lands them at the family’s first move into the flat, where Mia finally faces the truth: Doris’s affair, Ludwig’s role as Mia’s biological father, and the heavy cost of the life she’s trying to rewrite. Doris is briefly hospitalized during the event as she prepares to give birth, intensifying Mia’s shock.
With the truth laid bare, Mia confronts the consequences of time travel and the gravity of her memories. She returns to the present carrying Doris’s belongings in a box, and she carries a heavy resolve to let the past remain where it belongs. In the final quiet, Mia places the box at Doris’s grave and walks away, free to live the life she chooses, even as the truth about family and fate continues to echo in her steps.
