It's a special day in 1950s Harlem, and C. J., an aspiring young jazz musician, is excited. His trumpet-playing Uncle Click is getting ready to be photographed by Highnote magazine. When Uncle Click can't find his signature black beret, C. J. volunteers to retrace his uncle's steps from the previous day to find the hat. As C. J. races to Uncle Click's favourite hangouts, a buzz about the photo shoot begins to stir in the Harlem air. Soon all the best jazz musicians in the neighbourhood have shown up at Uncle Click's front door for a photograph of historic proportions.
