Regine manages her hospital ward with almost superhuman powers. Devotedly she takes care of her two children and her husband, who doesn’t contribute to their livelihood with the music he makes. Regine is in control - but of one thing: the appearance of Lily, who has been abroad for ages.
The much unloved sister appears always when Regine isn’t there. Quickly the children become all dotty about their new auntie and Regine hasn’t met her even yet. The situation slips out of her hands. The eerier it becomes, the crankier Regine gets.
Just before her whole world falls apart, she bravely faces the facts: the mysterious sister is herself. This explanation seems to make sense of all the strange happenings. But it’s too late already: family, friends and colleagues retreat. Regine is left alone and can’t even get hold of her second personality. Her life is lost. She takes the necessary steps. After she’s gone, Lily stays. Is she really her other personality, or has Regine been deceived?
