That morning, before the massacre begins, a student named Jason is being bullied and is struggling to pick up his books, but then Sean helps him.

Later, during a lunch period, Sean talks to his math teacher, Martin Blackwell, about the crush he has on his friend, April Lauren.

Meanwhile, Jason is left to fend for himself, but he does manage to make it out of the school, carrying out the body of a dead girl in the process.

Jonathan attempts to save his life, but after several minutes, Mr. Blackwell tells him to wait in the closet until help arrives.

Sean, Nick, Sam, and a few other students including their friend Mike, stumble upon a suburban area where the injured have evacuated.

Sean struggles to cope with April's death, and Jason learns that the security cameras at school captured him carrying the dead girl out, and that he is being hailed as a hero.

During the credits, the list of several school shootings from the past (including Columbine and Virginia Tech) are shown, along with the victims of the massacres.

A message is then displayed about how officers are now trained to set up a perimeter and move toward gunfire in a school shooting situation since Columbine.
