All's for the best in the best of all possible worlds. Isn't it?

Candide

A young woman, married to a wealthy man, but miserably lonely; trapped within a world ruled with an iron fist. Katerina is driven by a lust for life and for love. Her husband, though, is impotent; her father-in-law a tyrant. No wonder, then, that she longs to free herself from this yoke. When Sergei starts work on the family estate, she sees in him a chance for salvation. However, their subsequent affair marks the beginning of a descent into crime.
