Jane, a loving mother of two, has drowned her toddler son and is charged with his murder in this powerful examination of love, loss, and family legacy. When a prosecutor decides Jane’s husband Tom is partially to blame for the death and charges him with “failure to protect,” Tom’s attorney proposes a radical defense. He plans to create reasonable doubt about his client’s alleged guilt by showing that Jane’s genealogy is the cause of her violence, and that she inherited her latent violence in the same way she might inherit a talent for music or a predisposition to disease.
