This feature documentary is an exploration of the concept of dirt and impurity. From the slums of Kolkata to Vancouver's Downtown Eastside to a barbeque joint in Central Texas, Dirt digs deep into the webs of meaning and feeling attached to that deceptively simple 4-letter word. An odyssey into all things unclean, the film features animation to make Hieronymus Bosch blush and music from Godspeed You! Black Emperor.
