Zero Day brings us into the world of teenage best friends Andre and Calvin.

Self-named the 'Army of Two' they used video cameras to record everything relevant to their final 'mission.' Their video diaries provide a window into their chillingly ordinary lives, and as we get to know them we become seduced by their intelligence, their humor, their directness, the inward and outward expressions of their adolescence, and their terrible single-mindedness.

Unsentimental, unnerving and truly compelling, Zero Day points no fingers and wisely leaves it to the viewer to judge its characters. The film features non-professional actors, including the boys' real-life parents.
