So you don't forget (1970)

Sinopsis

Carmen, a woman in her twenties, records videos every day for her deceased mother. As a way of processing her absence, she captures what remains of their relationship in the echoes of daily life. One day, a new neighbor moves in next door — Carita, a 10-year-old girl, along with her mother, Amalia, who has begun to show signs of memory loss. Carita also records videos every day, but hers are for a father she has never met. From the very beginning, Carmen and Carita spy on each other through their cameras, building a silent bond. One night, Carita discovers a hole in the closet of her room. When she crawls through it, she finds herself inside Carmen’s apartment.
