The Hughes family has it all.
Big house, great jobs, the kids go to the finest schools. Nothing is too good for them.
They're living the American Dream.
Unfortunately, the family isn't the perfect family it appears to be. The family has secrets. Skeletons in the closet. And some secrets can kill.
When they wake up one morning to find that they have been entombed in their own home - every door and window nailed shut and covered with steel plating - they quickly realize that someone else knows their secrets, too. Someone who is willing to kill to destroy the secrets.
Even if it means killing the Hughes family to do it.
