You're Not Me (2023)

After an absence of three years, Aitana makes a surprise return home at Christmas so that her relatives can meet Gabi, her Brazilian partner, and their son. The reception from her parents is surprisingly very cold. Only her brother, who sits in a wheelchair, is pleased to see her again. But what affects Aitana most of all is the presence of a stranger her own age sleeping in her bed, wearing her clothes, living in her house, and treated by her parents as if she were their daughter. From that moment on, torn by jealousy, suspicion, and misunderstanding, Aitana tries to find out what is happening and who the intruder is that has taken her place in the family - until she discovers an unexpected and disturbing truth that is darker and way bloodier than she would ever have thought possible.
