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 teacher steps outside to issue a warning, but the student is gone, and the white line continues into the school building. So she follows it inside to find the student...
All she saw was the white line continuing 
straight beyond the edge of the roof.
كل ما رأته هو الخط الأبيض الذي امتدّ خلف حافّة السطح
Aber die Linie führte über das
gesamte Dach und darüber hinaus.
La línea blanca llegaba
hasta la baranda de la azotea.
La línea blanca llegaba
hasta la baranda de la azotea.
Il y a juste la ligne blanche
Tutto ciò che la giovane vide fu la linea bianca
che continuava dritta oltre il bordo del tetto.
Tudo o que viu foi a linha branca 
que passava direto pelo terraço.
