The Queen of Spades.

Based on Pushkin's short story: When his friends play faro, Germann always enjoys watching, but he never gambles himself. One day, as he is watching their game, he learns that an elderly countess staying nearby is said to possess a secret for winning a fortune at the game. Germann is determined to learn this secret from her, and he initiates a romance with her grand-daughter Liza, in order to improve his chances.
