3m, 3f / Drama Natasha Lisenko is twenty-two years old. She's clever, creative, can describe the plot of every episode of "Battlestar Galactica," and hasn't left the house in five years. Her sister, Lena, is an energetic, popular, occasionally cruel high-school cheerleader-or was, the last time Natasha saw her. As Natasha works her way through delayed adolescence and a strangely evolving relationship with her tutor, her family works to move forward without a sister, without a daughter, and without answers to the questions surrounding her disappearance. When the case is suddenly re-opened, Natasha is forced to make a decision. Reality or imagination? Make believe or truth? Or can she-as she's been doing for the past five years-go on existing someplace in between?
