In the gripping film "You Are Not Me," the protagonist Aitana returns to her childhood home after a three-year absence, bringing along her Brazilian partner, Gabi, and their young son. However, her homecoming is far from joyous as she is met with a surprisingly cold reception from her parents, who seem distant and uninterested in her life and achievements. The only warm welcome comes from her wheelchair-bound brother, who expresses genuine happiness at her return. This stark contrast in reactions leaves Aitana feeling isolated and confused, amplifying her sense of estrangement within her own family.
As Aitana settles back into the home that once felt so familiar, she is confronted by an unsettling reality: a young woman her age has taken her place in her old bedroom, wearing her clothing and seemingly enjoying her parents' affection. This stranger represents not just a physical presence in Aitana's life but a profound emotional threat that stirs a potent mix of jealousy, suspicion, and fear within her. The unsettling dynamics of her household force Aitana to grapple with her sense of identity and belonging, as she struggles to understand why her parents have embraced this person so wholeheartedly.
As the tension escalates, Aitana embarks on a quest to uncover the truth behind the mysterious intruder and her family's peculiar behavior. What she uncovers is a web of secrets and lies that leads her down a dark path, revealing unsettling truths about love, loss, and her family's history that she could never have imagined. This journey of discovery not only tests Aitana's resolve and understanding of her family but also forces her to confront what "home" truly means in a world where identities and relationships are easily blurred.
