Rome, 1905. Nadat hij haar verdedigd heeft tegen een opdringerige toeschouwer, wordt revuezangeres Lina Cavalieri op slag verliefd op de Russische prins Sergei, die als ambassadeur gestationeerd is in Parijs. Lina's klassieke muziekleraar Doria, die stiekem hoopt dat ze ooit zijn vrouw zal worden, neemt haar mee naar de Franse hoofdstad. Maar Sergei is daar niet meer; hij is teruggeroepen naar Rusland. Lina breekt met Doria en begint samen met de gitariste Carmela een succesrijk vaudevillenummer.
Nee, helaas is La donna più bella del mondo nog niet beschikbaar op Netflix in Nederland.
