Dimitri
Vasili returns to the Polish monastery where he was raised and reunites with Marina, who has disguised herself as a gypsy after fleeing an arranged marriage. The Count of Lusatia reveals that Vasili is Dimitri, son of Ivan IV. Lusatia and Vanda scheme to separate Dimitri from Marina and marry him to Vanda. Marina seeks Marpha, widow of Ivan IV, and tells her Dimitri is alive, but Marpha cannot confirm his identity. At Dimitri’s camp near Moscow, news arrives that Boris Godunov has been killed. Lusatia admits he murdered the real Dimitri; Dimitri kills him, and Marpha recognizes the young man as her son. Dimitri is acclaimed as leader, while Vanda swears revenge. At his coronation with Marina, Patriarch Job demands Marpha swear Dimitri is her son. As she hesitates, Lusatia shoots Dimitri, who dies with Marina and Marpha asking God to reveal the truth.
