Based on the critically acclaimed novel by John Burnham Schwartz, Reservation Road is a compelling tale of anger, revenge and great courage. The film follows two fathers as their families and lives collide.

On a warm September evening, college professor Ethan Learner (Joaquin Phoenix), his wife Grace (Jennifer Connelly), and their daughter Emma (Elle Fanning) are attending a recital. Their 10-year-old son Josh (Sean Curley) is playing cello - beautifully, as usual. On the way home, they all stop at a gas station on Reservation Road. In one terrible instant, he is taken from them forever.

On a warm September evening, law associate Dwight Arno (Mark Ruffalo) and his 11-year-old son Lucas (Eddie Alderson) are attending a baseball game. Dwight cherishes his time spent with Lucas. Driving his son back to his ex-wife, Lucas' mother Ruth Wheldon (Mira Sorvino), 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.
