Genre legend Joe Dante (The Howling, Gremlins) delivers hair-raising 3D chills with this visually immersive shocker about a pair of young siblings who discover a mysterious bottomless pit in their typical suburban basement. Shortly after moving from New York City to the quiet community of Bensonville with their single mother (Teri Polo), 17-year-old Dane (Chris Massoglia) and his ten-year-old brother, Lucas (Nathan Gamble), stumble across a locked trap door on their basement floor. Together with their new neighbor Julie (Haley Bennett), the two curious boys conduct a sequence of experiments in hopes of finding out exactly how deep the hole is, and what lies at the bottom. Later, just as the three youngsters begin to suspect that the hole reaches directly into infinity, a series of bizarre occurrences leave them convinced that something in the darkness has been waiting to escape, and that in order to defeat it they will have to face their greatest fears.
