Disgruntled office worker Bob Maconel (Christian Slater) is having another bad day at work. Trapped in his dull cubicle, mostly ignored by his co-workers and bullied by his superiors, Bob daydreams of blowing his office skyscraper sky-high, before ending his own miserable existence.

But on this particular day, Bob is transformed from potential killer into accidental hero when another stressed employee beats him to it and opens fire.

Unfortunately, going from zero to hero in the blink of an eye has its downside and soon Bob finds himself closer to the edge than ever before.
