chris and andre be two average and ordinary teen . misunderstood by some and pick on by others . but together they stand and all will pay . together they form the army of two . they scheme and plan zero day . that day be when they decide to storm their high school and inevitably murder 14 people in cold blood . tell through the tape that they make zero day and it be barely a fictionalized telling of the columbine tragedy . zero day be one of those movie that will mess with your head afterwards . the two main actor ( calvin robertson and andre keuck ) do such a good job that their character seem like almost any disenfranchised teen walk the street . their performance be very believable and you kinda like these guy and that be scary . shot on video almost totally from the teen perspective zero day feel very real and authentic and like you be right there . these kid try to rationalize their action to the viewer and the actor sell it to you . but be warn it do follow the tragedy from begin to end and the end make be shock and uneasy for some .
