Working as a humble cobbler, the Optimist (Enn Reitel) is thrown into an international world of crime and classical ballet when a diamond is stolen - the famous Light Fantastic. Beautiful dancer Olga (Karen Smith) is on the run from incompetent thugs when she hides the stone in a ballet shoe and draws the Optimist into a plot that leads to him being forced on stage to dance a pas-de-deux in Swan Lake with Olga and the Corps de Ballet to great acclaim.
