Am I a killer? The question haunts 25-year-old Jane Jensen. When she wakes up in the hospital after a devastating auto accident, she finds that her memory since ninth grade of high school has been wiped clean. As she heals, she begins to recover a memory here and there, and piece by piece, she tries to stitch it all together to restore the narrative of her identity. Jane is aware that she has gone from bullied, overweight schoolgirl to successful corporate wonk in the last several years. But when the wife of her teenage obsession gets killed in a professional hit, Jane makes yet another transition-to that of murder suspect. It's a situation that would be unbearable for anyone, but it's infinitely worse for Jane since she can't defend herself from the awful accusation for one major reason: Jane has no idea if she's innocent or guilty.
