A ballet class in the Parisian Grand Opera. A rehearsal of a famous dancer and choreographer. His dancing techniques are unfamiliar to the Ballerina, but his inspiring talent wins her over. The dancer becomes her Partner, their triumphal success is guaranteed. Her feelings for her Partner are not reciprocated. Her unrequited love and her loneliness in an alien world aggravate the symptoms of her mental imbalance. The Ballerina tries to forget her woes in the jovial atmosphere of Paris. But the ghosts of the past haunt her even here. The vestiges of the red revolution and delusional visions of the Chekist give her no peace. Even her favourite role of Giselle, which amazes the audiences and brings her worldwide acclaim, cannot bring her peace of mind. She shall follow Giselle’s fate: the betrayal of her loved one, madness. Mirrors shatter the great Ballerina’s sanity. Madness seems a welcome salvation, an escape into the glittering world “of the other side of the mirror”.
