Si muero antes de despertar

(1952) If I Should Die Before I Wake/ Si muero antes de despertar (In Spanish with English subtitles) THRILLER

Adapted from the short story by William Irish aka Cornell Woolrich it centers on a young boy, Lucho/ Luis Santana (Néstor Zavarce) interacting and bonding with the little girl student sitting on front of him. Started as soon as he purposely dipping her ponytail into an ink jar, we find out her name is Alicia Miranda (Marta Quintela). On the very next day, Luis then notices Alicia eating some sweets and wanted to have some as well. And before she hands him some, she then makes him swear to never reveal to anyone who she got it from. And then on the day after that, she then ends up missing. Detectives then go to the class to ask for any leads, except that Luis had remembered what he had promised, as he may have remembered the man who was hanging around in the school yard, and may have seen Alicia walk away with him. He then tries to make sense of it from his father, (Floren Delbene) who happens to be an inspector. And on the following day, he then bonds with the next student, Julia (Maria A. Troncoso) who coincidentally happen to also see the same man.

Although, this movie could be the base from "The Window" from 1949, it also has familiar rings to another movie called "M" from 1931 directed by Fritz Lang.
