Based on true events, Sarah, a vibrant teenage girl, looks forward to her 18th birthday so she can leave her controlling father, Don. But before she can blow out the candles, Don locks her in the basement of their home and her world goes very dark.

As time passed, Sarah gave birth to several children, alone in the basement .
