A prehistoric patient zero. An infectious primal hunger. Some discoveries are better left buried...

Research Station, Siberia. Madison Price would go to the ends of the earth to be part of archeological history. So when a team of scientists uncover an ice-preserved Neanderthal, she puts a personal tragedy to the side to exhume the body. But after one of the scientists starts exhibiting strange, violent symptoms, Madison fears their discovery has unleashed a lethal virus.

With the remote lab under a panicked lockdown, Madison's dream excavation decays into a waking nightmare. As more members of the team turn rabid, the archaeologist and the remaining survivors may be humanity's last hope.

Can Madison contain the epidemic before it's unleashed upon the world?
