A tale of anger, revenge, and courage that follows two fathers as their families and lives converge. On a warm September evening, college professor Ethan Learner, his wife Grace and their daughter Emma are attending a recital. Their 10-year-old son Josh, the pride of the family, is playing cello--beautifully, as usual. On the way home, they all stop at a gas station on Reservation Road. There, in one terrible instant, he is taken from them forever. On a warm September evening, law associate Dwight Arno and his 11-year-old son Lucas are attending a pivotal baseball game. Dwight cherishes his time spent with Lucas. Driving his son back to his Lucas' mother, his ex-wife Ruth, Dwight heads towards his fateful encounter at Reservation Road. The accident happens so fast that Lucas is all but unaware, while Ethan--the only witness--is all too aware, as a panicked Dwight speeds away. The police are called, and an investigation begins. Haunted by the tragedy, both fathers react in unexpected ways...as do Grace and Emma. As a reckoning looms, the two fathers are forced to make the hardest choices of their lives.
