One by One

.. Claire Matchett needs this trip. It will be a break from work and raising children. A chance to repair her damaged marriage. A week of hiking and hot tubbing with friends at a luxurious hotel in the woods, disconnected from the pressures of real life. Then, on a lonely dirt road, Claire's minivan breaks down. With no cell reception, the group has no choice but to walk the rest of the way to their remote accommodation. But the forest is dark and difficult to navigate and, hours later, they are lost. Hopelessly lost. As they venture deeper into the woods, the members of their party are struck down mysteriously, one by one. Are they being hunted? And by what―or who? As Claire's dream vacation descends into a nightmare, something becomes clear: only one of them will return home alive.
