In the picture-postcard community of North Vancouver, local bottle pickers haved turned the act of binning into a thriving subculture of shopping cart racing. Murray Siple, a former snowboarder and sport film director injured in a serious car accident ten years ago, returns to filmmaking to capture their story in the documentary Carts of Darkness. Shot in stunning high-definition and featuring tracks from Black Mountain, Ladyhawk, Vetiver, Bison, and Alan Boyd, of Little Sparta, Carts of Darkness borrows the cinematic language of extreme sports films to capture the risk and intensity of life lived on the very edge.
