The territorial dispute between Japan and Korea over the ownership of the Dokdo/Takeshima islets is not limited to state to state relations. In both countries there are citizens' groups actively engaged in protesting, lobbying and educating the public. This Island is Ours follows a Korean kindergarten caretaker with a background in student activism and a recently widowed Japanese housewife as they campaign tirelessly for the sovereignty of the tiny islets that are currently controlled by Korea, but also claimed by Japan. This film creates a rare insight into the lives of the two activists on both sides by presenting their parallel experiences from a neutral point of view.
