Return to Year Zero? focuses on Cambodia as the 10th anniversary of the fall of the Khmer Rouge approaches. As the Vietnamese prepare to pull out of the country after its 10-year stay to help secure and rebuild Cambodia, a high level of uncertainty and danger remains. The film takes a look into the villages and urban areas of Cambodia, drawing parallels to life during the Khmer and in the present. With streets once desolate and terror overgrown, Cambodia has finally begun to revitalize, as business and life return.
