Father-daughter archaeologists Miles (Denis O'Hare) and Nora Holden (Ashley Hinshaw) discover a unique pyramid that has been buried beneath the Egyptian desert for 5,000 years. Accompanied by a newswoman (Christa-Marie Nicola) and her team, the archaeologists enter the tomb and promptly become trapped. Hopelessly lost within the pyramid's labyrinthine structure, the group faces deadly perils that threaten their escape, including collapsing floors and bloodthirsty predators.
