Regresa (2010)

When her husband Ernesto (Jaime Camil) throws himself into work and refuses to start a family, Maria (Blanca Soto) begins to think he is having an affair and turns to hypnosis to help her understand her relationship. But when the therapist ends the session, she doesn't come back as herself. Instead, Maria is convinced she is a Basque princess from the 15th century, who is engaged to a prince from that time.
