A new teacher is staying after school grading tests for her class. When she glances out the window, she sees a student in an unfamiliar, old-looking school uniform, laying white powder lines in the schoolyard.

The footsteps of not just 
one person, but many.

los pasos de muchas personas.

Passi non di una sola persona, ma di molte.
Não era somente uma
 pessoa, eram várias!
