A masked whistle-blower leaks a disturbing video of human experimentation from a secret bio-research lab then disappears. His friends, a local news reporter and a pair of amateur bloggers, decide to find the lab and their friend while recording all the events. Their journey takes them to a remote site in the New Mexico desert where they access a bizarre labyrinth of underground tunnels. When they realize a biological contaminant has afflicted all the workers with a mysterious disease, what started as a rescue mission turns into a fight for survival and escape.
