Now, two years after the murder, David's starting his senior year and struggling to get on with his life. But still, the doubt remains: could someone in his small town know something about his mother's death? And when David uncovers troubling clues that lead to a deep family secret, he starts to wonder if his mother's death is tied to the scandal. Then one night, David spies his father burying an old rifle in a deserted lot near his house, and is left with one thought-is his own father the killer?
