Muichkine, a young Russian prince, returns home to St. Petersburg from a mental institution, determined to spread decency and kindness in the harsh and cruel world. He becomes betrothed to an innocent young girl while trying to save a less-innocent woman from her own travail, but jealousy and his own naivete conjoin to bring about unimaginable tragedy.

During this harsh winter, as Christmas approaches, Angélique, a poor child, is found by an old couple, Hubertine and Hubert. But this couple is not the richest, and the life of this small family is hard and laborious. Angélique likes to escape to the city, to dream. One day, she meets Félicien, with whom she falls in love. But she is told that this handsome man is the bishop's son, so marrying him is impossible.
