Rome, 1800: The city suffers from Scarpias, the Chief Constables, reign of terror. The seditious painter Cavaradossi falls into his clutches and is bound to be executed. His beloved Tosca – chased after by Scarpia – strikes a bargain: She answers his desires, and Scarpia will save Cavaradossi by a fake execution with blank cartridges in return. Scarpia agrees, approaches her – and she stabs him to death. But he, too, has not kept his word and ordered to shoot Cavaradossi with real ammunition. With a broken heart, she leaps to her death from the pinnacles of Castel Sant’Angelo.
