After proving his true identity, D'Eon gains the trust of Elizaveta. It is revealed that the Empress and Lia had been former friends and dedicated themselves to reform Russia. The Empress grants D'Eon and his companions permission to arrest Vorontsov, who turns out to be a nobleman who was once under her command. Bestuzhev and Vorontsov carry out their plan to assassinate the Empress, but are thwarted and deceived by D'Eon and his comrades. Elizaveta arrests Bestuzhev as a consequence and thanks the Four Musketeers for their service.
