On a warm September evening, college professor Ethan Learner (two-time Academy Award nominee Joaquin Phoenix), his wife Grace (Academy Award winner Jennifer Connelly), their daughter Emma and son Josh stop at a gas station on Reservation Road. That night, law associate Dwight Arno (Mark Ruffalo) and his 11 year old son Lucas are driving home from a Red Sox game on the very same road. There, in one terrible instant, 10 year old Josh is taken from his family forever. The accident happens so fast - Ethan, the only witness, runs to his son and panicked Dwight speeds away. The policed are called and hit and run investigation begins. Haunted by the tragedy, both fathers react in unexpected ways.
