Strange things have been happening recently, and Halley Scott has been paying attention. Over the last few weeks, mysterious meteors have been falling to earth unannounced, and not predicted by scientists. With the help of a heat seeking tracking device that uses radio waves (referred to as an "amplifier"), Halley and her partner Jon Howard track the biggest meteor yet to the remote location of an abandoned fort. Once there, supernatural events begin to ensue. Strange cries for help can be heard over the amplifier, and a mysterious beast pursues them and corners them inside the tunnels of the fort. Who are these cries for help coming from, and where did this beast come from? The answers might just make you question everything.
