From writer/director Richard Kelly ('Donnie Darko') comes this suspense horror, based on a short story by Richard Matheson and starring Cameron Diaz and James Marsden. When a little wooden box mysteriously appears on the doorstep of cash-strapped young couple Norma and Arthur Lewis (Diaz and Marsden), the secret it holds presents a moral dilemma which forces them to face the darkest depths of their humanity.
