3% (Surveillance Cameras in Streets)

In episode 2, Ezequiel is travelling through the streets of what they call The Inland. They are not supposed to go there, so he travels in disguise. Aline walks into a room where surveillance footage is shown in a room where the walls function as a large screen. 

Aline is in this moment trying to uncover what Ezequiel is hiding. She discovers that certain surveillance cameras attached in different streets and on different corners have been tampered with, each containing a blind spot where people seemingly disappear into nothing. Three circles follow the movement of the people in the footage, so when they disappear, so do the circles as there no longer is any motion to track.

She resets the cameras to show the full image that they are supposed to record, and discovers a hunched figure walking through the streets, and recognise it as being Ezequiel. When Aline virtually follows him through the streets with the different camera angles, we also see those three circles that indicate motion tracking following him.
