The game begins as Eric Harris' mother wakes him on April 20, 1999. Harris phones Dylan Klebold, and the pair meet in Harris' basement to plot a series of bombings that will precede their planned shooting. The two reminisce about the bullying they experienced at Columbine High and express rage at those they perceive to be their tormentors. Harris and Klebold make a video, apologizing to their parents and asking them not to blame themselves for what will follow. The two boys collect their guns and bombs, pack a duffel bag with weapons, and leave home.
