# and a group of men to perform magic. Rasputin has a vision and
# denounces one of the men as a horse thief. Although his father initially
# slaps him for making such an accusation, Rasputin watches as the man
# is chased outside and beaten. Twenty years later, Rasputin sees a vision
# of the Virgin Mary, prompting him to become a priest.
# Rasputin quickly becomes famous, with people, even a bishop, begging for
# his blessing. <unk> <unk> <eos> In the 1990s, the remains of Russian Tsar
# Nicholas II and his family were discovered. The voice of <unk> young son,
# Tsarevich Alexei Nikolaevich, narrates the remainder of the story.<eos>

# In 1991, the remains of Russian Tsar Nicholas II and his family ( except for
# Alexei and Maria ) are discovered. The voice of young son, Tsarevich Alexei
# Nikolaevich, narrates the remainder of the story. 1883 Western Siberia, a young
# Grigori Rasputin is asked by his father and a group of men to perform magic.
# Rasputin has a vision and denounces one of the men as a horse thief. Although
# his father initially slaps him for making such an accusation, Rasputin watches
# as the man is chased outside and beaten. Twenty years later, Rasputin sees a
# vision of the Virgin Mary, prompting him to become a priest. Rasputin quickly
# becomes famous, with people, even a bishop, begging for his blessing. In the
# early 20th century, Rasputin became a symbol of the Russian Orthodox Church.
# The image of Rasputin was used in the Russian national anthem, " Nearer, My God,
# to Heaven ", and was used in the Russian national anthem, " " ( " The Great Spirit
# of Heaven "
