Two girls dream of being dancers - but only one, Tracey, has talent. The other has ideas: about rhythm and time, about black bodies and black music, what constitutes a tribe, or makes a person truly free. It's a close but complicated childhood friendship that ends abruptly in their early twenties, never to be revisited, but never quite forgotten, either. Dazzlingly energetic and deeply human, 'Swing Time' is a story about friendship and music and stubborn roots, about how we are shaped by these things and how we can survive them.
