Conquest

Napoleon Bonaparte (Charles Boyer) launches an unsuccessful seduction of the Countess Marie Walewska (Greta Garbo), who is married to a much older man (Henry Stephenson), but she resists until convinced that giving in will save Poland. After her husband annuls their marriage and Napoleon divorces the Empress Josephine, the pair are free to formalize their happy relationship, but Napoleon shocks her by announcing his decision to wed the Archduchess Marie Louise of Austria for political reasons. While he doesn't expect it to impact his relationship with Marie, she leaves him, without ever telling him that she is expecting his child.
