Aurora Borealis is a family story with plentiful of twists taking place on two separate timelines. It analyses the relationship between a mother and a daughter in great depths. Mária (Mari Törőcsik), the elderly mother of Olga (Ildikó Tóth), the successful attorney living in Vienna, unexpectedly falls into a coma. While Mária is hovering between life and death, Olga comes across a deliberately withheld secret. The increasingly passionate investigation takes her back to the war-torn Europe of the 50s; where, at the end of her journey she discovers herself: a woman she never knew before. The film discusses the dramatic situations originating from identity crises with feminine sensitivity in unusual situations, the never-healing wounds caused by the wars of the shattered Europe, passing, and the liberating powers coming from unveiling lies and suppressions.
