On a warm summer day, Cami Novarro heads to her grandfather's cabin to help him clean up the last of the remaining miscellaneous items he needs to be removed prior to selling the place. Little did she know that several bad seeds were on their way to the property to use as an outpost for a terroristic plot they planned to carry out. The evildoers are unaware she's there as they murder her grandfather and proceed to lay out their plan. Cami is trapped in the labyrinth walls of the old, isolated home that once served as a transport point for liquor bootleggers. She must remain completely silent as she navigates the hidden tunnels of the cabin in an attempt to escape the foreigners who have invaded her family's vacation spot. Any noise and any wrong move could alert the dangerous men of her presence. With no cell phone service and one path for entry and exit, Cami has limited options for getting away. She must use her wits and instincts in order to survive the ordeal.
