Beneath the blazing desert sun, Tahoe Manoa has opened a strange puzzle box. The box is an odd inheritance passed down to him by his great-grandfather, a long dead Cherokee warrior. As the box opens, the desert atmosphere suddenly changes. Struck by sudden fear, Tahoe stands helpless as dark, shadowy figures surround him in the desert. After fleeing the shadows, Tahoe realizes they are haunting him. The shadows, poltergeist in nature, have even made physical contact. He immediately boards a flight to Pittsburgh and enlists the help of the paranormal investigators, but before arriving in room 208, Tahoe learns the shadows have followed him. Growing up, Tahoe heard legends of such entities-shadow walkers, more commonly known as shadow people. Soon, the shadows haunt each of the investigators, spreading their presences like a contagion. Their intent is the theft of human souls. Now, Tahoe and the investigators must discover the origin of the shadows and vanquish them forever-before it's too late.
