The Geoje POW camp sits on an island at the southernmost part of Korea.
In the summer of 1951, U.S. Army officer General Roberts, comes up with a strange morale-boosting plan. He asks Sergeant Jackson, a former Broadway performer, to teach some of the prisoners to tap dance, hoping they can put on a show that will get the camp favourable media attention.
Soon enough a tiny ensemble emerges all on its own. The band of prisoners call themselves ‘Swing Kids’, and together find a new sense of freedom in dancing. But the reality of war is always close and their dreams are put to the test.
