The weight of sadness

Delilah is a 20-year-old girl who suffers from depression. She decides to start recording daily videos with her camera and uploading them to the Internet as a way to vent. But her videos only have a few views. One night, Delilah decides to go for a walk through the center of Mexico City to record another video. As she walks alone, she notices that the streets are deserted, which is very strange. Suddenly, she hears screams and sees people collapsing.
