The beginning of this PSA looks like an ad for school supplies — a new backpack and folders. But as the next student puts on his headphones, it becomes clear the spot is about something else altogether.A student runs down the hallway, another uses her jacket to try to lock doors, another breaks windows with a new skateboard to let students escape. And finally, a girl hides in a bathroom stall, crying, texting "I love you mom," as we hear someone coming in.
