Scene 1: St. Petersburg
Onegin, having traveled the world for many years in an attempt to escape from his own futility, returns to St. Petersburg where he is received at a ball in the palace of Prince Gremin.
Gremin has recently married, and Onegin is astonished to recognize in the stately and elegant young princess, Tatiana, the uninteresting little country girl whom he once turned away. The enormity of his mistake and loss engulfs him. His life now seems even more aimless and empty.
