1 Hour Photo is the story of Mas Yamamoto, a man whose life was swept up by the major currents of the 20th century. From growing up in a fishing village on the banks of the Fraser River, to being confined at a Japanese Canadian internment camp during World War II, to helping build the Distant Early Warning Line in the Canadian Arctic during the height of the Cold War, 1 Hour Photo is a moving portrait saturated with the most vivid colours of our times.
