In 1806 Nikolai Rezanov arrived in California, then a part of New Spain, to get provisioning for Russian settlements in Alaska. Maria fell in love with Rezanov and they got engaged. To marry Maria, a Catholic, Rezanov had to obtain the Emperor's permission. He also had to sail back to Alaska. On his way back to Saint Petersburg he fell ill and died in Krasnoyarsk in 1807 at the age of 43. A year later, Alexander Andreyevich Baranov told Maria the news, but she would not believe it until 1842 when Sir George Simpson gave her a detailed account of Rezanov's death. She took a vow of silence and lived in a monastery in Monterey, California until her death in 1857.
In the fall of 2000 the sheriff of Benicia, California, where Maria is buried, brought a handful of earth and a rose from her grave to Rezanov's grave in Krasnoyarsk. The cross on the grave is engraved with "I will never forget you" on one side and "I will never see you again" on the other, referencing a line from a popular track of the opera performed by a male and a female singer.
Voznesensky never claimed historical accuracy in his account, stating that characters in his poem are images echoing the fates of real people.
Plot
After his wife's death, Court Chamberlain Rezanov decides to commit himself entirely to the service of Russia. His attempts to arrange trade with North America are not well received at government, but finally he is ordered to organize the expedition he desires. Before his departure, Rezanov tells a story that has been bothering him since his youth. Once he saw the icon of Our Lady of Kazan and since then he feels he is in love with Mary. Mary visits Rezanov in one of his dreams and tells him not to be afraid of his feelings, promising to pray for him.
Two ships, Juno and Avos, under Russian Navy Ensign are leaving for California. In then-Spanish California, the governor is preparing for the wedding of his daughter Conchita and Sir Fernando. Rezanov greets the Californians on behalf of Russia and the governor invites him, as the ambassador of Czar Alexander, to the 16th birthday ball for his daughter. Nikolai asks Conchita for a dance, which turns into a fateful event in the lives of the two and Fernando. Fernando is jealous, and guests cynically make bets on whether Rezanov will "pluck the California flower". Both men, Fernando and Rezanov, understand that neither one will give up without a fight. At night Conchita prays to Mary, and Nikolai comes to her room. The two fall in love and secretly become engaged.
But good fortune is no longer on Rezanov's side. Fernando calls for a duel. The Russian-American company business is in decline. The scandal prompts the Russians to leave San Francisco. On his way back to Saint Petersburg, Rezanov falls ill and dies in Krasnoyarsk. Conchita dies in a Dominican monastery.
