Shortly after noon on an otherwise ordinary day at DeKalb Elementary school, Steven (
Bo Mitchell), a mentally unstable man in his 20s, enters the front office and asks if he can use the phone. He then pulls out a semi-automatic rifle.
After he orders the school receptionist, Cassandra (Tarra Riggs), to have the building evacuated, he holds her hostage and tells her to call 911. With Cassandra as his go-between, Steven tries to navigate the troubled waters he has entered.
Inspired by an actual 911 call placed during a shooting incident at Ronald E. McNair Discovery Learning Academy in Atlanta, Georgia.
